Do you ever watch old nature documentaries or sci-fi flicks from the 1970s just for the loopy soundtracks? You know, the kind of spacey arpeggios and synth chords that were designed to accompany footage of a Galapagos tortoise, but somehow transcend the dated schtick of it all? Panabrite (the nom de plume of Seattle keyboardist Norm Chambers) makes music like that: fibrilating whorls and whooshes that inhabit that strange space between the intimate and the epic. “Rainbow Sequence” and “Camembert Symphony” are two cuts off this year’s Soft Terminal LP: the former a glittering, skittering mid-tempo song with a flourish of R&B, the latter a more driving, persistent dance track. Both selections recall Epcot, circa 1979: futuristic, fun, and heartwarmingly campy.
