Information:  - Trip hop is a subgenre of electronic music that originated in the early 1990s in the United Kingdom, especially Bristol. Deriving from later idioms of acid house, the term was first used by the British music media and press as a way to describe the more experimental variant of breakbeat emerging from the Bristol Sound scene, which contained influences of soul, funk and jazz. It has been described as "Europe's alternative choice in the second half of the '90s", and "a fusion of hip hop and electronica until neither genre is recognisable". Trip hop music fuses several styles and has much in common with other genres; it has several qualities similar to ambient music, and its drum-based breakdowns share characteristics with hip hop. It also contains elements of R&B, dub and house, as well as other electronic music. Trip hop can be highly experimental.  - Gorillaz are a British virtual band created in 1998 by Damon Albarn and Jamie Hewlett. The band consists of four animated members: 2D (lead vocals, keyboard), Murdoc Niccals (bass guitar, vocals), Noodle (guitar, keyboard, and backing vocals) and Russel Hobbs (drums and percussion). These members are completely fictional and are not personas of any "real life" musicians involved in the project. Their fictional universe is explored through the band's website and music videos, as well as a number of other media, such as short cartoons. In reality, Albarn is the only permanent musical contributor, and the music is often a collaboration between various musicians. Writers and critics have described their music as alternative rock, Britpop, trip hop, hip hop, electronica, indie, dub, reggae and pop.  - Electronica is an umbrella term that encompasses a broad group of electronic-based styles such as techno, house, ambient, drum and bass, jungle, and industrial dance, among others. It has been used to describe the rise of electronic music styles intended not just for dancing but also concentrated listening.  - Morgan Daniel Nicholls ( born 18 March ) is an English musician , member of Senseless Things and best known for performing with Gorillaz , The Streets , Muse and most recently Lily Allen . He released one solo album under the name Morgan .  - Reggae is a music genre that originated in Jamaica in the late 1960s. The term also denotes the modern popular music of Jamaica and its diaspora. A 1968 single by Toots and the Maytals "Do the Reggay" was the first popular song to use the word "reggae," effectively naming the genre and introducing it to a global audience. While sometimes used in a broad sense to refer to most types of popular Jamaican dance music, the term "reggae" more properly denotes a particular music style that was strongly influenced by traditional mento as well as American jazz and rhythm and blues, especially the New Orleans R&B practiced by Fats Domino and Allen Toussaint, and evolved out of the earlier genres ska and rocksteady. Reggae usually relates news, social gossip, and political comment. Reggae spread into a commercialized jazz field, being known first as Rudie Blues, then Ska, later Blue Beat, and Rock Steady. It is instantly recognizable from the counterpoint between the bass and drum downbeat, and the offbeat rhythm section. The immediate origins of reggae were in ska and rock steady; from the latter, reggae took over the use of the bass as a percussion instrument.
