Wiwi: Loreen gave Wiwi a scare when she delivered sub-par vocals during her first rehearsal earlier this week. Thankfully the Swedish diva has benefited from some rest: she gave it to us full throttle, and in perfect harmony, this morning at the Baku Crystal Hall. Loreen unveiled her costume as well. It’s basically the same pantsuit from Melodifestivalen, but she’s taken some scissors to her wings. The shredded fabric goes flying every which way when she howls into her wind machine. Together it gives the performance an extra-crazy vibe to match the “Euphoria” of love she sings about in her song. It may be time to book your tickets to Stockholm for ESC 2013.
