Sonnymoon, a Boston-based quartet of Berklee College of Music grads (read: total music nerds), are fronted by the beautiful, floating vocals of Anna Wise. Her name should be familiar to any Kendrick Lamar fans, for her ethereal, Badu-esque performance on “I’m Real.” But her music with Sonnymoon, as heard on their self-titled, self-released LP last year, takes a much more expansive approach, with truly other-worldly musical backdrops that borrow from electronica, hip-hop, jazz, Bjork, Flying Lotus and everything in between. Their opening set at the Roots Picnic in Philly will be by far their biggest live set to date, and should catapult them to even bigger stages very soon.
