Portland indie-folk troubadours Ages and Ages stopped by the PRP studios Friday for a surprise mid-afternoon acoustic live session, and rocked the place with their by-this-point-unmistakable interlaced harmonies and infectious living-room sound.

Ages — who broke out with a first album in 2011 that Willy Week immediately pronounced “classic” — haven’t disappointed in the years since, producing two more stellar releases and a wonderful acoustic NPR Tiny Desk Concert. The band played Doug Fir Friday, almost a year to the day since their last show in their hometown, amid a slight mid-tour reprieve back home. On Sept. 23, they’ll make a stop at Stackstock, the new festival in Cannon Beach, before heading out east for the rest of the fall.

Take a listen to their studio session at PRP below, and catch them at the beach in a couple weeks.
