The Barr Brothers’ second CD, Sleeping Operator, wonderfully showcases the quartet’s sublime and compelling world-folk sound. The brothers, guitarist Brad, and drummer Andrew, toured for 15 years in The Slip, a top jam band. After moving to Montreal, they met harpist Sarah Page and bassist/pianist Andres Vial, and together have created their quieter and more song-centered ensemble. Sleeping Operator comes after a very creative period where they wrote more than 40 songs, featuring lyrics by Brad Barr and exotic instrumentation. The result is a CD that’s intimate, evocative and at times otherworldly.
