Blues-rock jam band Blues Traveler [ tickets ] set out on a US outing last weekend that will make its ways across the country through September.

At the moment, the band has a busy April calendar, followed by a few dates per month in May, June, July, August and September. The itinerary is listed below.

The Grammy-winning band is still supporting 2005's "Bastardos!"--its eighth studio album and first for Vanguard Records. The set, produced by solo artist and ex-Wilco multi-instrumentalist Jay Bennett, followed 2003's "Truth Be Told" as well as the CD/DVD collection "Live on the Rocks," which documents Blues Traveler's shows at the famed Red Rocks Amphitheatre near Denver.

Recently, the group contributed its version of "Rag Mama Rag" to tribute album "Endless Highway: The Music of The Band," which surfaced in January.

Blues Traveler formed in Princeton, NJ, in 1983 and went on to become one of the decade's more successful touring groups. In the '90s, the group founded the H.O.R.D.E. festival as an outlet to tour several jam bands.

One of a few groups in the jam genre to be accepted at pop radio, Blues Traveler put out its most commercially successful album, "Four," in 1994, scoring multiplatinum status and hit singles "Run-Around" and "Hook."

In related news, frontman John Popper wrapped a Colorado tour earlier this month with his side band, The John Popper Project, which features DJ Logic, Blues Traveler bassist Tad Kinchla and Mosaic drummer Marcus Bleecker. The group's self-titled debut was released in October.
