Two of the most legendary bands in American music history have made their way to the Rocky Mountains to play at the best concert venue this country has to offer tonight. Rock legends Chicago and The Doobie Brothers will share the stage this summer evening for a night of classic rock hits spanning both artists’ extensive repertoire of chart topping and award winning hits.

Each band will perform individual sets, playing their biggest hits, and then both Chicago and The Doobie Brothers will join together for a thrilling grand finale encore, playing each others songs at the end of the night.

Chicago, the legendary band with horns, and the highest charting American band in Billboard Magazine’s list of Top 100 artists of all time, will once again allow a winning bidder to have a once-in-a-lifetime opportunity to sing the band’s classic hit song, “If You Leave Me Now” onstage with Chicago at every concert. This is the third consecutive year that Chicago has teamed up with the American Cancer Society to create “Sing With Chicago,” a highly successful promotion that has raised over $130,000 to fight breast cancer.  Fans in every market will be able to bid on a package that includes a meet and greet with the band, two premium tickets and a chance to sing onstage in concert with the band. Fans can bid in the auction here, and all proceeds directly benefit the American Cancer Society’s fight against breast cancer.

Northern California’s The Doobie Brothers are celebrating the 40th anniversary of their propulsive roots-based, harmony laden, guitar driven style that sold an estimated 40 million records over the course of four decades. In 2010, original members Pat Simmons and Tom Johnston, and 30-year member John McFee marked a new chapter with the delivery of a potent album, World Gone Crazy, featuring a guest appearance by the legendary Willie Nelson.  It’s their first new album in a decade, and it produced the Top 20 track “Far From Home.”
