Now that Jeff Tweedy's thoughts on all those "dad rock" jokes are known once and for all, Wilco can get back to focusing on straight-up rocking -- and the band is already preparing to do just that, confirming plans to bring back the Solid Sound Music and Arts Festival next summer. The gathering is set for June 21-23 at the Massachusetts Museum of Contemporary Art in North Adams, Mass.

Wilco will hit the stage for two sets during the gathering and once again curate the music lineup. Three-day "early worm” tickets are available for a limited time via the festival’s official website for $99, discounted $50 from the normal price; a very limited number of single-day tickets will go on sale early next year.

The inaugural Solid Sound Music and Arts Festival took place in the summer of 2010, with Wilco both curating and headlining. Various Wilco side projects --  the Autumn Defense, Pronto, the Nels Cline Singers and Tweedy solo -- were also on the bill, which was rounded out by the Books, Mavis Staples, Avi Buffalo, Outrageous Cherry, Richard Bishop and Vetiver. Wilco brought back Solid Sound in 2011 but skipped this summer due to the demands of launching their own label.
