2011 has been a big year for CrystalStilts, who will be bringing their psychedelic pop and minimalistic sound to Brooklyn’s KnittingFactory on Dec. 9. The five-piece released their second full-length, In Love With Oblivion, but the momentum didn’t stop there for the group. Recently Crystal Stilts put out an EP titled Radiant Door, which is out on Sacred Bones Records and was produced by the band’s own JB Townsend. Tickets are $12; doors at 7 p.m. The show is all ages.
