From a Mercer Island gig last fall, that’s Swamp Soul, the Cajun/Zydeco band that’s on a double bill with Neil Young tribute band Ragged Glory at this Thursday night’s Admiral Neighborhood Association-presented Summer Concerts at Hiawatha show. Third one so far and both have drawn hundreds – it’s a big lawn, though, so plenty of room, even if you can’t get there till the last minute. 6:30 pm, east lawn of Hiawatha Community Center. Then on Friday night, Providence Mount St. Vincent starts its four-week Summer Concerts at The Mount series, and has rejoined WSB as a sponsor to promote the shows, which also are free. First up, this Friday, it’s the Duwamish Dixieland Jazz Band, seen here in a June performance:

The DDJB opened last year’s Summer Concerts at The Mount, too. Food goes on sale (as does beer/wine) at 5 pm, music at 6; special activities will be available for kids, too. Go here for the full schedule of the four-week series at The Mount, and here for the full schedule of the remaining four weeks of the six-week series at Hiawatha. (Bring your own chair/blanket for both.)
