Two Three interesting events to profile this week. The first is actually a three-day musical extravaganza to celebrate The Boston Phoenix’s Best Music Poll, with some very cool local bands in free performances at Downtown Crossing. This includes everything from psychedelic to lo-fi punk, synth-propelled New Wave and dance, indie pop, folk, and Americana. Secondly and a late addition because I just realized they’re performing at the Milky Way in JP Friday night, Audrey Ryan and Shepherdess, two highly talented singer-songstresses. The third promises to be a fun and adventurous evening of cabaret and music from Bent Wit Cabaret. They present a full collaborative theatrical production on the second Sunday of every month at OBERON in Cambridge (Harvard Square). For this particular show (“Identity”) which commemorates the end of Pride Week, they’ll be exploring race, sex, and gender, with lots of music, from rock to jazz to pop.
