Low makes its first appearance on Mountain Stage, recorded live in Grand Marais, Minn., in partnership with the North House Folk School. Led by the husband-and-wife team of Alan Sparhawk and Mimi Parker, Low's ethereal, understated rock sound grew out of a reaction to the grunge music that was in vogue when the band formed; in the early days, Low would turn its amplifiers down to goad audiences into listening.

The Tuscon, Ariz., band Calexico has made a career out of warping genres and musical traditions together into an eclectic, clever, original mix. Drawing upon jazz, alt-country, post-rock and a wide-ranging variety of Latin styles from mariachi to cumbia to Tex-Mex, Joey Burns and John Convertino (along with an ever-rotating cast of supporting players) have crafted a uniquely inclusive vision of indie-rock Americana.

Alt-J (stylized as ∆) may be the most successful new British band of 2012 — a favorite to win the Mercury Music Prize in November and a Top 20 chart phenomenon in the U.K. The group, which chose its name from the mathematical symbol for change, made a splash with its debut album, An Awesome Wave, which came out in September. The record mixes upbeat indie rock and brooding synths with vocals that sound like no one else's in music today.

The Great American Canyon Band is a Baltimore indie-folk act featuring husband-and-wife duo Paul and Krystal Jean Masson. The pair's first single, "Tumbleweed," is a lovely, dreamy piece of countrified rock, destined for road trips. The rest of the self-titled EP came out in May, and an additional track, "Young Lady," was released on Sept. 5; it's available for download here.

Big Joe Turner's hardest-hitting singles have been collected on a new compilation, titled Big Joe Turner Rocks.
