There are four artists with the name Diesel. 1) Diesel is an up-and-coming dubstep producer from the UK who often distributes his music through Inspector Dubplate. Characterized by insanely tweaked percussion and fiercely filthy basslines. http://www.youtube.com/DieselBeatsUK
2) Diesel was a Brazilian post-grunge/alternative rock band. After releasing one self titled independent record and playing the famous Rock in Rio festival, the group left Brazil for the US. There they reformed and changed their name: they are now called Udora.
