The Mars Volta

Born from At The Drive-in, they are amazing, to me.  Post-punk, psychedelic, patterns in/on patterns, prog-y.  Sometimes they get way out there, but one of the bands I listen to frequently.  Some of their songs I would say I overplay!  They are often intense at the same time as settling into a groove.  So any band that can take seemingly contradictory things and make beautiful pieces of art is worth listening to for me.
