We’re over at the Crowley Theater, just starting rehearsals for This Clement World, the musical performance piece by Cynthia Hopkins that addresses the global climate crisis (and will eventually be part of the Carbon 13 exhibition). If you’re still in Marfa tonight, don’t miss this work-in-progress — I got chills listening to Cynthia just do vocal warmups. Show starts at 8 pm. Free. — NI
