Styx, REO Speedwagon and Don Felder will team up this summer for the United We Rock tour.

It starts on June 20th in Ridgefield, Washington and runs through August 22nd in Holmdel, New Jersey. Tickets for select shows go on sale February 24th at LiveNation.com.

Though Styx has toured with both REO and Felder, this is the first time REO and Felder will have hit the road together.

REO singer Kevin Cronin actually broke the news last month aboard the Rock Legends Cruise when REO and Felder shared the stage for a Q&A session [with Premiere Radio's Sal Cirrincione], but what's said at sea stays at sea.
