Steely Dan and the Doobie Brothers

Two rock mega-stars co-headline the Summer of Living Dangerously Tour. Steely Dan, which lost co-founding member and songwriter Walter Becker in September, continues to deliver their famously sophisticated blend of jazz, progressive rock and pop with Donald Fagen, Becker’s longtime musical partner, at the helm. The band had a run of seven platinum albums in the 1970s and early '80s, including classics like "Aja" and "Gaucho." They reunited for 2000's "Two Against Nature," which garnered several Grammys. The Doobies started life as a California blues-rock outfit in 1970, producing radio staples like “Listen to the Music,” “Jesus Is Just Alright,” “Long Train Runnin’” and the No. 1 hit “Black Water.” They then pivoted into pop with new frontman Michael McDonald, knocking out Top 10 singles like “Takin’ It to the Streets,” “Real Love” and “What a Fool Believes” into the early 1980s.
