Sister Squares — composed of Miles Francis, Julie Shore, Jenny Shore, and Sara Dobbs — have supported former Arcade Fire member Will Butler on tour as he’s promoted three albums under his own name, but the decision to call his latest project Will Butler + Sister Squares came from a desire to collaborate earlier on in the writing process. The album the groups collaborated on includes equal parts recordings from Figure 8 studio in Brooklyn, group experiments from Butler’s basement, and sessions in drummer/co-producer Miles Francis’ Synthia Studio. The groups perform tonight at the Grog Shop in Cleveland Heights. Singer-songwriter Rachel Bobbitt, who's touring behind her new EP EP The Half We Still Have, opens the show.
