Episode 161: Bluegrass has an instrumental tradition going back to its Bill Monroe origins and its old-time forebears. Over time, the playing and composing became more refined and exploratory. This show features three young masters of contemporary acoustic music who've released all-instrumental albums in recent months. I speak with Wes Corbett, banjo player currently with the Sam Bush Band, Jeff Picker, bass player for Ricky Skaggs and Kentucky Thunder, and Andrew Marlin, half of the married duo Mandolin Orange. They talk about their new recordings and about the path that led them to write and record without words.
