The Mars Volta - De-Loused in the Comatorium

As an At The Drive-In diehard, I was at this show a month before this album dropped. The band was opening for The Chili Peppers for an arena tour and to end the East Coast leg, Mars Volta did a one off at North Six in Brooklyn (650 person venue). Flea played bass with MV, and John Frusciante was in the crowd. 4 days after this show MV member Jeremy Ward (sound technician and vocal operator) died of a heroin overdose. This was his last show.
