Jam-grassers Yonder Mountain String Band make their way back to the region for a performance at the Bardavon. The hard-touring Colorado quintet combines bluegrass with rock, jazz, and progressive improvisational sounds and topped the bluegrass charts with their eponymously titled fourth studio album in 2006. As their series of live Mountain Tracks albums shows, it’s on stage where YMSB shines brightest, so lovers of dazzling fretwork, keening high harmonies, and exploratory instrumental flights should line up for this one. $39-$49.
