Surely when Joan Soriano  left his Dominican fishing town for the bright lights of bachata central Villa Mella -- at 13! -- he couldn't have anticipated that a San Francisco culture writer's fireworks hangover would be alleviated by his NPR concert. There you have it, however. Let Soriano take away that Fifth of July (red, white, and) blues on the coattails of his jingling, mellow notes. For more Soriano, check out his gigs at Cafe Cocomo  on Fri/6 and Impala  for "Hot Bachata Nights" on Sun/8.
