Few violinists in modern times have made as much of a mark on the music world as Darol Anger. A founding member of the Turtle Island Quartet, he now teaches at the Berklee School of Music in Boston. I caught up with Darol at the Wintergrass Bluegrass Festival in Bellevue, Washington, and here he talks about the physical challenges of playing the violin and some of the exceptional violins he has had the opportunity to tuck up under his chin.
