MATRIXSYNTH spotted this surreal video from modularman. It starts off with some cheesy banjo, before becoming synthy and ominous. This is a really fun find! Note that the thumbnail is not Eric Idle in drag.
Don't let the banjo intro fool you, this turns into a full blown synth-fest pretty quickly! Features the Roland System 8, Dave Smith Instruments Tetra, Bebot, Yamaha MX 49, Roger Linn Adrenalinn III, and others.
