This week's live broadcast comes to you from the Ravinia Festival in Highland Park, Illinois, where you'll find some of the most wonderfully elaborate picnic spreads east of the Mississippi. Add the mid-summer happenings in Lake Wobegon and it's all right there on your local public radio station this Saturday evening. Rich Dworsky and the crisp quartet of Richard Kriehn, Jonathan Dresel, Larry Kohut and Chris Siebold will deliver summer stuff for the live broadcast, and work on remaining hydrated for the big non-broadcast sing-along that always follows our Tanglewood show. Sara Bareilles and Nadia DiGiallonardo team up to belt Broadway melodies out into the Berkshires, and radio drama abounds with The Royal Academy of Radio Actors - Tim Russell, Sue Scott, and sound effects man Fred Newman. Rachel Manke is traveling light with her ukulele, and Peter Rowan adds some Old School bluegrass straight from the Big Mon tradition. Sarah Jarosz joins us with her arsenal of instruments for songs and duets with the host, and she'll be back with us in late July for our big cross-country tour. This week: our penultimate live broadcast of the season, from the Koussevitzky Music Shed at Tanglewood in Lenox, Massachusetts. Light the sparklers, spin the pinwheels, and we'll see you on the airwaves for one more live broadcast before we load up and hit the road for our exciting summer tour. Also: a crush of characters from Tim Russell and Sue Scott, and sound effects man Fred Newman sparks fireworks and rockets music director Rich Dworsky and the band ( Bernie Dresel, Larry Kohut, Richard Kriehn, and Chris Siebold) serve up sweltering slices and the News from Lake Wobegon, with the tried and true traditions of Independence Day in the tiny town.

Butch Thompson adds his quintessential piano and clarinet, Tjärnblom rounds things out with a celebration of Minnesota's Scandinavian heritage, and the Macalester College Pipe Band brings some Celtic spirit.

There's great American music with JD McPherson, rock-solid rambles from Joe Newberry, and roof-raising soul from Jearlyn and Jevetta Steele. This week: it's back to where it all began, Macalester College in Saint Paul, Minnesota, for our Second Annual 40th Anniversary Live Broadcast and 4th of July Season Finale.
