Chris Cohen’s tender voice has a way of kicking your heart around for days at a time. Softly crooning into your ear, his melodies are psychedelic ear worms, swimming in starry pools of electric piano atop buoyant waves of bass and drums. This Sunday at the Lilypad, open up your rapidly cooling heart and let those waves wash over you. Supported by the mellotron sighings of Cambridge locals Beach Toys and the dream-weaving folk of Lina Tullgren, it’s your best bet for an ALL AGES early winter revival. Snow’s not here yet, folks!! Get to the gig!!
