In random order:
Massive Attack, Tricky, Kyuss, Queens of the Stone Age, Bob Dylan, Monster Magnet, Van Morrison, Nirvana, Gorillaz, Beck, DJ Shadow, Primus, Morcheeba, De Staat, The Doors, The Animals, Flogging Molly, Soundgarden, The Pogues, Blur, Radiohead (I have to clarify this one: OK Computer is absolutely brilliant. The rest I find 'okay'), Big Bad Voodoo Daddy, Causa Sui, Dan Le Sac versus Scroobius Pip, Rage Against The Machine, Shpongle, Roosbeef, The Prodigy, Truckfighters and Orange Goblin.
Probably more. Although I must add, I don't really have a favorite bands. These are just artists I love. Depending on the mood and time, I love some more than others.
