At first, Bucks County favorites Illinois might seem like your average indie-pop band, crafting the sort of warm, laid-back tunes that manage to jump from meditative, folk-inflected pop (“Where’s My Woman”) to synth-heavy R&B excursions (“Hang On”) and back again without breaking a sweat. But you’d be quite mistaken to assume they aren’t ambitious. Just last year they completed their grand narrative The Adventures of Kid Catastrophe, six EPs now available as one album and accompanied by a short movie. Though frequent lineup changes in recent years have plagued the hard luck indie fuzzy folk rockers, hopefully Arch and the gang will have some sexy costumed ladies doin’ “the brick dance” tonight at The Blockley where they’ll be joined Stereolab-esque Rubblebucket and earthy soul entertainers Sister Sparrow and the Dirty Birds.
