Two legends of Classic Rock will join forces on stage at the Pepsi Center June 12th as Steely Dan and The Doobie Brothers will bring their Summer of Living Dangerously tour to Colorado.

This will be the first tour for Steely Dan since the death of co-founding member Walter Becker this past September.

Tickets start at $49.50 and go up to $129.99. They go on sale this Friday (Jan. 12) at 10am through altitudetickets.com. For you Citi cardholders, you get a pre-sale Wednesday morning (Jan. 10) at 10am.

Here's a tribute from Donald Fagen, Walter's bandmate and co-founder of Steely Dan.
