Arbouretum + Pontiak + Coconuts

The syrup-slow psych-pop of Baltimore's Arbouretum flows in sleepy, spooky waves on 2009's Thrill Jockey–released LP Song of the Pearl; a recent (thrilling) show had Matt Sweeney guesting. Tonight the band joins labelmates Pontiak, a trio of brothers who produce thickly warped, dark rock songs on their latest, Sea Voids.
