"The Lost Gig" [mp3 removed -- tune is now on Bandcamp]
The insectile buzzing background thing is an FM-modulated LFO sweeping a high pass filter (modular/hardware). Graphically the waveform resembles a Slinky flexing.
The "lead" is another LFO sweeping a wavetable in a chord (softsynth). The lament is half digits, half voltages.
Dedicated to friends slapped down hard by the Invisible Hand just because it can.
