DARTZ!
Dartz were a Math rock group from Middlesbrough in North East England (UK) who formed at the beginning of 2005. They are signed to Xtra Mile Recordings in the UK and Deep Elm in the US, and have to date released one full-length album, one mini-album, three singles and a split 7" via Xtra Mile - as well as an EP on Sunderland based DIY micro-label Fakedream Records and a split 10" with Scottish band Stapleton on Gravity DIP.
They have recorded with illustrious producer Mark Williams (Biffy Clyro, Bloc Party, Fightstar, Nine Black Alps, Million Dead etc) at the world famous battery studios in London and they've toured with groups such as Get Cape Wear Cape Fly, Hot Club De Paris and The Rumble Strips, as well as also playing with bands including The Futureheads, Melt Banana, The Young Knives, Make Believe and Foals. More recently Dartz added long-time collaborator Nico Taylor, once the logistics man for the band, to the line-up.
In September 2007, the band announced that they were going to take a break from touring to focus on their education, with Maughan studying English Literature at Oxford University and Anderson studying English and Film at Sheffield Hallam.[citation needed] The decision was explained in an article in The Times newspaper entitled "Bands Balancing Uni With Fame", although it was criticised by the NME in the magazine's review of "The Sad History Of The Village Of Alnerique" in September 2008.[citation needed] Dartz have had three videos featured on MTV2, all of which were directed by Teesside University lecturer Marcus T. Diamond. A fourth video, for the track "Cold Holidays", was recorded by Wife Swap cameraman Rob Taylor during the band's tour with I Was A Cub Scout.
They broke up on July 2nd 2009 according to their MySpace page.

Rock Music
Rock music is a genre of popular music that entered the mainstream in the 1950s. It has its roots in 1940s and 1950s rock and roll, rhythm and blues, country music and also drew on folk music, jazz and classical music. The sound of rock often revolves around the electric guitar, a back beat laid down by a rhythm section of electric bass guitar, drums, and keyboard instruments such as Hammond organ, piano, or, since the 1970s, synthesizers. Along with the guitar or keyboards, saxophone and blues-style harmonica are sometimes used as soloing instruments. In its "purest form", it "has three chords, a strong, insistent back beat, and a catchy melody."
