Screaming Plastic are an electrified free improv quartet from Omaha, NE that record their cello/electric guitar/electric bass/drum kit (and barrage of effects pedals, of course) jams live to I-Phone 6s with minimal editing and zero overdubs.
Concerning these two recordings, the progression from 1’s stoccato, textured hollows of percussive intra-instrumental rapport to 2’s thicker, exponentially more fulfilled layerings is quite something to behold and it makes back to back listens between these two albums all the more rewarding, contrasting the two.
