If your initial assumption was totally far-out, psychedelic jams, then you were absolutely correct. Cedric and Omar have always been known to be experimental workaholics when it comes to music and, even in between bands (At The Drive-In and Mars Volta), they were pushing their limits and creating art that sounds fresh and interesting. If you like anything else that these guys have done together (or separately), you should probably check out their new stuff that they're putting out as Antemasque.
