Expansion includes one track with the drummer playing a prepared Buchla synth.  Never heard of Zeitlin before, but the instrumentation (electric piano, clavinet, ARP, kalimba, Buchla) kinda said, "buy me."  The album itself mixes acoustic post-bop with free synth freakouts-- often within the same song-- which seems to make it even more disorienting than expected.
