Bleep, Bleep, Bloop

From its first slow-building tones to the last, mind-altering buzz of feedback, this Boston-based trio finds the meditative eye in a hurricane of sound. Like their post-rock predecessors -- Slint, Gastr del Sol, A Minor Forest -- they bring a difficult, carefully-plotted orderliness to swirlingly improvised sounds. They navigate tricky rhythms and odd time signatures as if they were inevitable, taking the listener along for the ride to a parallel universe. There is a narrow line between hypnotic and repetitive, and the band stays on the right side, introducing enough change to keep things interesting, enough of the same motifs to allow for reflection.
