that performance looks better than a religious experience
a few years ago i found these "hypno glasses" at a garage sale
^much like these but not home made....basically large glasses that have different red lights which create a pattern to the music played through the connected player....so in my mind a portable Dream Machine
it came with all these tapes on how to control your mind to get mates, or money, or confidence etc etc....some really weird yet horrible stuff...lots of ocean sounds also
i experimented with sounds ranging from punk to power electronics to minimal ambient....still put them on from time to time
i also was lucky enough to have constant access to a sensory deprivation tank...which had a wonderful sound system built into it....i don't really think i can describe the experiences i had with music and the float tank.....but would say in many ways they were life altering
