After a season’s hiatus from releasing albums, it’s funny that Constellation Records, a label known for epically brooding and despair-obsessed post-rock, should put out an album with cover art drenched in pink. Glissandro 70 is a studio-based outlet for Sandro Perri of Polmo Polpo and Guitarkestra’s Craig Dunsmuir to loosen the technicolor leanings their full-time outfits hold in check. It’s in such stark contrast to the rest of the label’s back catalog (save, possibly, Le Fly Pan Am) that it feels like Constellation’s normal digs — by railroad tracks, abandoned factories and warehouses — have been uprooted and moved to Fraggle Rock. There’s still a little bit of disquietude in the mixture of discordant instrumentation and what-kind-of-club-is-this? disco/funk rhythms, but it hinges more on absurdity than apocalypse; although the Mike Patton-esque percussive vocals on “Portugal Rua Rua” are fairly frightening. Perhaps the closest contemporary would be the Pinback offshoot Howard Hello, as both bands pick up on the rubbery soul in Talking Heads’ affection for world beat. It’s ideal for springtime excitement and drunk on summer expectation. Apparently after years of lamentation, Constellation is finally letting the sun shine in. It sounds pretty good from here.
