Gorillaz is the virtual band you might recognize from the Clint Eastwood music video, Feel Good Inc, Saturnz Barz (Spirit House) or the new album, specificly Humility!
They wuz created in 1998 by musician Damon Albarn and artist Jamie Hewlett to spice up MTV.
Damon is also independant and was singer for the band Blur. You may recognize Blur for the song "Song 2" (it was on Just Dance 2 for the Wii. I would know that cuz my mom forced me to playit to exercize, albeit the fact im quite active due to ADD)
