Nonesuch Records releases Michael Daves’s two-album set, Orchids and Violence.Both discs are produced by Daves and have identical track listing of mostly traditional bluegrass songs. The first features straightforward interpretations of them and was recorded live to tape in a 19th-century church by Daves and a band of roots-music innovators: bassist Mike Bub, violinist Brittany Haas, mandolinist Sarah Jarosz, and Punch Brothers banjo player Noam Pikelny. The second disc was recorded in Daves’s home studio and includes bass, drums, and electric guitar, mostly played by Daves, and takes a raw, experimental rock approach to the same old-time material.
