The Cure’s set at Spain’s Bilbao BBK Live got off to a rocky start tonight — but was all the more memorable for it. As the band’s crew worked on keyboard problems, Robert Smith took the stage by himself and treated the crowd to a rare solo-acoustic set , performing “Three Imaginary Boys,” “Fire in Cairo” and “Boys Don’t Cry.”

The Cure continues to move forward with its plan to headline seemingly every festival in Europe this summer, with three new additions to Robert Smith and Co.’s itinerary: Primavera Sound 2012 in Barcelona, Spain; Bilbao BBK Live in Bilbao, Spain; and Optimus Alive in Oeiras, Portugal.
