You might have seen Sleepy Kitty before you heard them: The Cherokee Street duo's Technicolor concert posters have spread across town like the flu, and principal members Paige Brubeck and Evan Sult are an inseparable fixture at local events and shows. The pair's music, however, is just as striking. Brubeck's time-warp vocals can be unadulterated (think Cat Power on Broadway or Regina Spektor sans affectation) or distorted, as they float above vaguely distressed piano, askew guitar chords and other found sounds. Like a lullaby appetizer for a nightmare-laden main course — or the entertainment at a block party in Edward Scissorhands' neighborhood — Sleepy Kitty explores beauty's unsettling underbelly. If you missed Brubeck and Sult covering askew indie-wranglers Pavement at An Under Cover Weekend, don't fret. They'll be opening for cabaret-pop darlings the Dresden Dolls at the Pageant in November.
