Open House creates compellingly strange pop songs that sprawl into sonic landscapes through the use of movement, choreography, and staging. The band’s new piece Rememberer uses amplified eight-foot-long sheets of Styrofoam wall insulation, erected into teetering structures that vibrate, hum, squeak, and seem destined to collapse. Architecture doubles as instrument in this collage of music and live construction directed by Steven Reker, which will be performed at the BAM Next Wave Festival in October. Their mini-residency at Knockdown Center culminates with a short open rehearsal performance.
