The title of Wobble, the 15-minute, seven-track EP released by Drew Williams in February, isn’t a reference to twerk culture. Instead, the adventurous saxophonist and composer created a study in unbalanced electronic glitchiness. Looped ambience swirls in, out and around saxophone tones. The vociferous “Squeal” is almost certainly one of the year’s most exciting statements by a locally based musician. A set of corresponding videos provides a second means of experiencing the work.
