The return of the massive Hardly Strictly Bluegrass festival is always a massive lift for music lovers all over the Bay Area, particularly with a lineup that once again leans heavily on its ‘hardly strictly’ mantra and has booked an array of bands across the musical landscape. Organizers of the event, as usual, are making sure that the event benefits the larger Bay Area community, and is doing so by continuing its “Hardly Strictly Out of the Park,” a series of nighttime live performances at a handful of venues around town, including a quartet of shows at our own venerable Sweetwater Music Hall.
