If you're not in the mood for Joanna Newsom's epic, medieval-fantasy song cycles at Benaroya tonight, consider seeing Architecture in Helsinki, Australia's best export since Steve Irwin (RIP). The orch-pop sextet leaps from twee swooning to upside-down funk to aeronautic anthems with energy and ease. The Showbox's spring-loaded floor is sure to be bouncing. Opening is Panther, Portland's absurdist white-boy Prince, and nu-Italo disco darlings Glass Candy. It's an oddly matched but totally brilliant bill. (Showbox at the Market, 1426 First Ave, 628-0888. 8 pm, $16, all ages.)
