Right around the time that temps are finally heating up, Hotel Vitale and its waterfront restaurant Americano are launching their third annual Sound Check summer concert series. The event kicks off Wednesday night and goes through September, and will feature acoustic performances by emerging artists, starting with Kill Rock Stars lady duo Thao & Mirah. All the performances will go down on Americano’s usually crowded 3,000-square-foot outdoor patio with views of the Bay Bridge. Indie acts Body Language and Penguin Prison will hit the stage in August and September, respectively. Best part: They're all free!
