After slogging through a sweltering, sweat-drenched day there is certain contentment that comes from a warm Washington night. This good humor was evident Saturday night at the Black Cat, where a sizeable crowd came out for cheerful indie kids, Tilly and the Wall. The Omaha based group was joined by their label mate, David Dondero, and locals, Exit Clov.

The near overwhelming dominance of X marked hands showed the youth of the headliner’s fan base, though no scene was in great evidence. All were brothers and sisters though by the time Exit Clov took the stage.

“We just rolled out of bed and came here.” said Susan Hsu of Exit Clov. She and twin sister, Emily, have joined The Breeders and Tegan and Sara in the noble tradition of twin frontwomen. The band proceeded to belie Hsu’s statement, playing an energetic opening. With harmonies falling somewhere between The Dixie Cups and The Ditty Bops, the Hsu sisters’ vocals were tight and sweet. The instumentation was servicable with the only weakness being “minimalist” guitar solos that seemed over before they began.
