Ohio blues-rock duo The Black Keys [ tickets ] will set out on a US trek in early November, backing the recent release of "Magic Potion," the band's fourth album and first for Nonesuch Records.

The duo will employ a variety of opening acts on its upcoming outing, which kicks off Nov. 2 in Boston. Texas indie rockers The Black Angels, supporting their April debut, Passover," will support on the first couple of weeks of shows, through a Nov. 18 date in Cleveland.

Indie-rockers Dr. Dog will take over the support reins Nov. 25 in Chicago and finish up the rest of the tour with the Keys.

Staffed by guitarist Dan Auerbach and drummer Patrick Carney, The Black Keys [ tickets ] formed in their hometown of Akron, OH, in 2002, and issued their first album, "The Big Come Up," the same year.

Undeterred by an almost complete lack of income, the pair set out across the United States in a beat-up hatchback, according to their official bio, playing small clubs whenever they got the opportunity. Semi-fame beckoned when Rolling Stone magazine gave "The Big Come Up" a four-star review.

Auerbach and Carney recorded and produced "Magic Potion," which follows 2004's acclaimed indie release "Rubber Factory," in Carney's basement studio on Akron.

"Unlike all the other records, where we were just trying to figure out how everything worked, or pretending like we knew what we were doing by experimenting with mic placement, this one we just figured out what we liked and stuck to it," Carney said in a press release. "The whole record has a more consistent sound, and it's a little bit heavier than our other records."
