Just a goofy little jam using sequences from the 251e. This was the 214,547th take, so I just went with it.
Leading rhythm voice is Buchla 259e main oscillator and Bass is 259e modulation oscillator.
The Lead is 261e set up with tracking and timbre modulation. The percussion is just noise sequenced by the 251e.
The rhythm voice and the lead are each sent through a 267e filter.
The rhythm filter's frequency is modulated with a mix of its own envelope, and fluctuating random.
The 261e lead's filter, symmetry, timbre, and modulation index are controlled by the left X/Y pad on the K-controller (unfortunately off-camera :-\).
Tech notes

Recorded on a Sony PCMD50 digital recorder. Video shot on a Sony A6000 with a Canon 24mm tilt-shift lens to give a bit more DoF.
