Blood Orange, Angel Olsen, and Stephin Merritt have joined the lineup for this year’s 31st Annual Tibet House US Benefit Concert. They join the already-announced guests Philip Glass, Rhiannon Giddens, and the Resistance Revival Chorus, the latter of whom performed with Kesha at the Grammy Awards this past weekend. The concert will take place on 3/3 at Carnegie Hall. Tickets are available here.
