Rock legends Styx, Foreigner and former Eagles star Don Felder are teaming up for a U.S. tour. The trio of acts will hit the road for The Soundtrack of Summer trek, which kicks off in Oklahoma in May (14). Styx guitarist James Young tells Billboard.com, "I look at it like we're a bunch of old heavyweight fighters getting together. It's very exciting to be out there together, 30 years after we all had number one albums and everything. And having (Felder), who was an obvious contributor to the writing side of the Eagles and does lots of Eagles songs in his show, that will make a nice complement. "It has the potential to be the most successful of anything we've ever done with us in a co-headline position like this." Styx previously toured with REO Speedwagon and Ted Nugent in 2012.
