Autobahn is a trio that’s been playing publicly for three years, and their first release Filler Migration is a triple-single. What does 333 signify again? If that’s too mystical for you, just listen to the songs. They’re far less sunny than the Kraftwerk record the band shares a name with. It’s textbook no wave totalism; they’ve referred to their sound as “bubblegum Glenn Branca.” Opener “7 Window Still” pulses and sways, with disaffected delivery distracting from a constant high-pitched hum. This almost imperceptively shifts into “C-Side,” where cello is deployed in only a way a band that owns a singing saw could pull off. “Alter Song” has a sweetness that defies its primitive drums and feedback. I would be remiss not to mention the record’s title, which refers to a twisted side effect of attempting to achieve physical perfection via augmented reality. All of those art school papers paid off.
