Ya, Mars Volta is crazy. And Ab, the reason they tour with the Peppers is because bassist Flea and guitarist John Fuciante(?) of the Red Hot Chilli Pepers often play with The Mars Volta. And At the Drive-In isn't neccisarily better, It's a whole nother field of music so It's hard to really compare them... Both are just amazing strides for their given genres. Any of you guys listened to the original band, De Facto? I'm really curious what that group sounded like.
