3. Grunge
Sometimes referred to as the Seattle sound) is a sub-genre of alternative rock that emerged during the mid-1980s in the American state of Washington, particularly in the Seattle area. Inspired by hardcore punk, heavy metal, and indie rock, grunge is generally characterized by heavily distorted electric guitars, contrasting song dynamics, and apathetic or angst-filled lyrics. The grunge aesthetic is stripped-down compared to other forms of rock music, and many grunge musicians were noted for their unkempt appearances and rejection of theatrics.

4. Blues Rock
Is a hybrid musical genre combining bluesy improvisations over the twelve-bar blues and extended boogie jams with rock and roll styles. The core of the blues rock sound is created by the electric guitar, piano, bass guitar and drum kit, with the electric guitar usually amplified through a tube guitar amplifier, giving it an overdriven character.

5. Cello Rock
Cello rock and cello metal are subgenres of rock music and heavy metal characterized by the use of cellos (as well as other bowed string instruments such as the violin and viola) as primary instruments, alongside or in place of more traditional rock instruments such as electric guitars, electric bass guitar, and drum set.
Cellos, often in groups of three or more, are used to create a sound, rhythm, and texture similar to that of familiar rock music, but distinctly reshaped by the unique timbres and more traditional genres of the cello (in particular) and other string instruments used. The cellos and other stringed instruments are often amplified and/or modified electronically, and often played in a manner imitative of the sound of electric guitars. They are often combined with other elements typical of rock music such as rock-style vocals and drumming.

6. Psychedelic Rock
A style of rock music that is inspired or influenced by psychedelic culture and attempts to replicate and enhance the mind-altering experiences of psychedelic drugs. It often used new recording techniques and effects and drew on non-Western sources such the ragas and drones of Indian music.
Psychedelic rock bridged the transition from early blues- and folk music-based rock to progressive rock, glam rock, hard rock and as a result influenced the development of sub-genres such as heavy metal

7. Metal Deathgrind A musical genre that fuses death metal and grindcore
Death metal is an extreme subgenre of heavy metal. It typically employs heavily distorted guitars, tremolo picking, deep growling vocals, blast beat drumming, minor keys or atonality, and complex song structures with multiple tempo changes
Grindcore is an extreme genre of music that started in the early- to mid-1980s. It draws inspiration from some of the most abrasive music genres – including death metal, industrial music, noise and the more extreme varieties of hardcore punk. Grindcore is characterized by heavily distorted, down-tuned guitars, high speed tempo, blast beats, and vocals which consist of incomprehensible growls, or high-pitched shrieks

8. Dance-Rock
A post-disco movement connected with post-punk/no wave genres with fewer R&B/funk influences, originated in the early 1980s, following the mainstream death of punk rock and disco
Allmusic defines "dance-rock" as 1980s and 1990s music practised by rock musicians, influenced by Philly soul, disco, and funk, fusing those styles with rock and dance

9. Afro Prog
a term that has been used to describe music of the late 1960s and 1970s that has both a distinct African cultural flavour as well as a progressive rock approach
Progressive rock bands pushed "rock's technical and compositional boundaries" by going beyond the standard rock or popular verse-chorus-based song structures; the arrangements often incorporated elements drawn from classical, jazz, and later world music. Instrumentals were common, while songs with lyrics were sometimes conceptual, abstract, or based in fantasy.

10. Alternative
a genre of rock music that emerged from the independent music underground of the 1980s and became widely popular by the 1990s
The New York Times defined alternative rock as "hard-edged rock distinguished by brittle, '70s-inspired guitar riffing and singers agonizing over their problems until they take on epic proportions".
Sounds range from the gloomy soundscapes of gothic rock to the jangling guitars of indie pop to the dirty guitars of grunge to the '60s/'70s revivalism of Britpop. More often than in other rock-styles since the mainstreaming of rock music during the 1970s, alternative rock lyrics tend to address topics of social concern, such as drug use, depression, and environmentalism.

11. Melodic Death Metal
a heavy metal music style that combines elements from the New Wave of British Heavy Metal (NWOBHM) with elements of death metal
Melodic death metal uses components of NWOBHM, in particular the fast riffing and harmonic guitar lines, but also is influenced by the characteristics of death metal like heavily distorted guitars, fast double-bass drum patterns and sometimes blast beats. The vocal style of the genre is a combination of harsh screaming, clean harmonies, and death growls

12. Art Rock
is a subgenre of rock music that originated in the United Kingdom in the 1960s, with influences from art, avant-garde, and classical music
art rock was a form of music which wanted to "extend the limits of rock & roll", and opted for a more experimental and conceptual outlook on music
Art rock took influences from several genres, notably classical music, yet also jazz in later compositions. Art rock, due to its classical influences and experimental nature, has often been used synonymously with progressive rock
Common characteristics of art rock include album-oriented music divided into compositions rather than songs, with usually complicated and long instrumental sections, symphonic orchestration,[1] and an experimental style. Art rock music was traditionally used within the context of concept records,[1] and its lyrical themes tended to be "imaginative",[1] philosophical,[5] and politically-oriented.

13. Punk
Formed as a response to the stagnation of rock and as a political statement in the ‘7os
The music was filled with contempt for previous styles, its fast tempo songs, usually propelled by electric guitar, featured irreverent lyrics often obscured by dangerous music

14. Jazz Rock
The term "jazz rock" is often used as a synonym for the term "jazz fusion".
Allmusic states that the term jazz-rock "may refer to the loudest, wildest, most electrified fusion bands from the jazz camp, but most often it describes performers coming from the rock side of the equation." The guide states that "jazz-rock first emerged during the late '60s as an attempt to fuse the visceral power of rock with the musical complexity and improvisational fireworks of jazz. Since rock often emphasized directness and simplicity over virtuosity, jazz-rock generally grew out of the most artistically ambitious rock subgenres of the late '60s and early '70s: psychedelia, progressive rock, and the singer/songwriter movement."

15. Electronic Rock
also commonly referred to as synthrock, electrorock or digital rock, is rock music generated with electronic instruments. It has been highly dependent on technological developments, particularly the invention and refinement of the synthesizer, the development of the MIDI digital format and computer technology

16. College Rock (Covers Many Genres)
College rock is a term that was used in the United States to describe 1980s alternative rock before the term "alternative" came into common usage. The term's use of the word "college" refers to campus radio stations located at institutions of higher education in Canada and the United States, where the term "college" is considered to be interchangeable with the term "university". These stations were the majority broadcasters of this music, as the stations' playlists were often created by students who preferred underground rock music.

17. Rap Rock
Rap rock is a cross-genre fusing vocal and instrumental elements of hip hop with various forms of rock.
rock songs in which the vocals were rapped rather than sung
the rhythms of rap rock are rooted in that of hip hop, with more funk influences than normal hard rock

18. Lo-Fi (Not a Genre)
is lower quality of sound recordings than the usual standard for music. The qualities of lo-fi are usually achieved by either degrading the quality of the recorded audio, or using certain equipment. Recent uses of the phrase have led to it becoming a genre, although it still remains as an aesthetic in music recording practice. Many lo-fi artists use inexpensive cassette tape recorders. The term was adopted by WFMU DJ William Berger who dedicated a half hour segment of his program to home recorded music throughout the late '80s under the name Lo-fi.

19. 2 Tone
is a music genre created in England in the late 1970s by fusing elements of ska, punk rock, rocksteady, reggae and New Wave

20. Alternative Dance
is a musical genre that mixes rock subgenres with electronic dance music
alternative dance mixes the "melodic song structure of alternative and indie rock with the electronic beats, synths and/or samples, and club orientation of post-disco dance music“
The genre draws heavily on club culture for inspiration while incorporating other styles of music such as synthpop, acid house, and trip hop. The performers of alternative dance are closely identified with their music through a signature style, texture, or fusion of specific musical elements.[2] They are usually signed to small record labels.

21. Art Punk
refers to post-punk music of an experimental bent, or with connections to art school, the art world, or the avant garde
