The itinerary isn't too heavy yet, but US dates are starting to roll in for Steely Dan [ tickets ]'s spring/summer Heavy Rollers '07 tour.

The jazz-rockers start off May 6 with a performance at the New Orleans Jazz & Heritage Festival and move on to East Coast casinos and theaters through early June. Steely Dan's website hints that more dates are on the way. Confirmed shows are listed below.

The band--led by co-founders Donald Fagen and Walter Becker--toured the US extensively in 2006 after taking a break for a couple of years. Steely Dan was on the road in 2003 to support its most recent album, "Everything Must Go," released that year. The cut "Slang of Ages" marks Becker's first lead vocal on a Steely Dan studio record.

The group's previous album, 2000's "Two Against Nature," was Steely Dan's first new studio set in 20 years and earned the band three Grammys in 2001, including Album of the Year. That same year, Steely Dan was inducted into the Rock and Roll Hall of Fame following a three-year, tongue-in-cheek campaign on the band's website.

Fagen, who also toured last year behind his latest solo release, "Morph the Cat," added another Grammy trophy to his mantle this month when the record took the Best Surround Sound Album category.
