r/OmBand

So lemme first say this i have the vinyl version and am a DJ and producer (techno/drone). My question is as follows : what is the sound heard @ 2:30, the high pitched synth/bagpipe/cymbal release? what is it? cause 1 dude plays the bass (Al) and the other drums (Chris). I would really like to know the anwser - burning for knowledge and revelation. thx
