This record was a collaboration between Omar Rodriguez-Lopez and his close friend Jeremy Michael Ward that took place shortly after Omar left cult post-hardcore band At the drive-in and began The mars volta in 2001. It features field recordings of various objects, activites and people that they later messed with in the studio. Jeremy died of an drug overdose in 2003, only a month before The mars volta released their first full length record Deloused in the comatorium (that featured lots of Jeremy's sound manipulations). I actually never think it was supposed to be released at first, but with Jeremy's death you can see the relase (it came out in 2008) as a tribute to Jeremy from Omar. All in all it's a noise classic that you shouldn't miss.
