C36 on Banned Production from 1999. Banned Production is a seminal noise/"experimental" label from the U.S. that is run by AMK (who is also a member of Big City Orchestra). It is still very much in operation and you should check it out!
M.S.B.R. was Koji Tano's epic Molten Salt Breeder Reactor whilst Speculum Fight used to be the alias of Damion Romero.
