Popper is the frontman of the group Blues Traveler.
Set for release Tuesday, his side project is the result of a monthlong recording session in the mountains of New Mexico.
Popper's record label said in a news release this week the "Duskray" project is "much less a solo endeavor as opposed to a fully realized band featuring guitarist/producer Jono Manson, bassist Steve Lindsay, drummer Mark Clark and guitarists Kevin Trainor and Aaron Beavers."
The band will embark on an extensive U.S. tour that kicks off in Seattle next week.
"Blues Traveler vocally and harmonica-wise involves a lot more acrobatics. The harp-playing is a lot more subtle on [the Troubadours'] album. I have melodies to cling to," Popper told the Portland Tribune.
