Known for slow-paced instrument-driven music and layered vocals, Low formed in Duluth, Minn., 20 years ago. Their debut album, I Could Live in Hope, came out in 1994 and won over fans thanks to its minimalist sound and its delicate harmonies from husband and wife Alan Sparhawk (vocals and guitar) and Mimi Parker (drums and vocals). The two originally teamed up with high school–student John Nichols (bass), who was ultimately replaced by Steve Barrington. Over the years, Low (above, doing “Monkey” live on KEXP FM) have added electronic-music flourishes to their work as they’ve continued to record new material, including this year’s acclaimed Jeff Tweedy–produced The Invisible Way (stream it below), all while remaining known for their live performances.

Mike Doughty—who at one time worked the door at the Knitting Factory—fronted the NYC quartet Soul Coughing in the ’90s. But when they broke up in 2000, he decided to go it alone, releasing his first solo LP, Skittish, which he’d actually recorded four years earlier. Doughty (below, performing “Na Na Nothing,” also for KEXP) has been a busy man ever since, touring, putting out more albums and even finding time to become a blogger and author known for his sense of humor. But currently, he’s on the road with Low. And you can see them both tonight at Music Hall of Williamsburg.
