Even as 2016, a year full of major losses in the music world, finally settles in the rear view, the healing must go on. In that spirit, 2017 will likely be even more chock full of commemorative/tribute shows and rock vigils for the array of talented dead. This Friday at Limelight, just such a tribute show will be dedicated to the memory and music of David Bowie. The show, which goes down just two days before what would have been the avant-pop icon's 70th birthday, will feature performances from The Flying Buttresses, Captain M.A. Zing, Ma & God, and Mount Pressmore. Proceeds from the small cover charge will go to fund cancer research in Bowie's honor, in the form of a donation to the Cancer Therapy and Research Center.
