Classic rock bands REO Speedwagon and Chicago are set to embark on a co-headlining North American tour this summer (14).

The groups will play 15 dates in major cities in the U.S. including New York City, Boston, Massachusetts and Dallas, Texas.

Chicago's Robert Lamm, says, "It's ironic, that these two legendary bands, who both have roots in Illinois, were labelmates... in the (1970s), and experienced waves of immense success in the (1980s) and (1990s), and have somehow continued to consistently make compelling music, both in-studio and on tour.... have never before performed together!

"This situation is about to change, as Chicago and Reo will perform together during the concert's encore and present a finale that will thrill their audiences. As a musician who has always respected Reo's skills, I look forward to our first rehearsals early this summer. This will be fun!"

Reo Speedwagon's Kevin Cronin, adds, "With so many personal connections between various members of Reo and Chicago, it is amazing that we have never actually toured together. I love it that the Chicago guys feel the way we do about truly playing together when you tour together...

"This tour promises to deliver some unique music from two bands who have made a ton of hit records, share that Midwest work ethic, and still refuse to sit back on their past accomplishments. We both keep raising the bar, challenging ourselves, and rocking hard... and the audience is the ultimate winner. We are psyched... I can't wait for this tour."

The tour will kick-off in August (14).
