The Wilco Solid Sound Festival will be held August 13-15 at MassMoca. Tickets go on sale Friday. Kind of a bummer that the biggest pop music event in who-knows-how-many years in the Berkshires is occurring when very few students will be in town … still, this is a major coup for MassMoca, and for North Adams in general. If you aren’t familiar with Wilco, you should be. Yankee Hotel Foxtrot is inarguably one of the ten best albums of the aughts.
