Celebrate the release of Mobile Freedom Home, the sophomore LP from Roof Doctor, tonight at PhilaMOCA. Mobile Freedom Home finds Roof Doctor in a finely polished place; each song seems to carry a natural, casual groove. Mark Harper’s lyrics offer an odd, comforting effect, one that generates a welcoming atmosphere in spite of their melancholy tone/message. Roof Doctor is rather deceptive musically, at first the sound appears simple; however, that simplistic vibe is a byproduct of tightly knit compositions rather than sparse instrumentation. Eclectic noise-rockers Mumblr alongside the sleepwalking sonic experimentalists Son Step. Long Island’s Soda Bomb round out the evening blending a variety of rock with garage/punk tendencies.
