The Black Crowes are known to go on hiatus. In 2011, after a couple decades of much success with the Black Crowes, singer Chris Robinson decided to use that particular sabbatical to do something new. He formed the Chris Robinson Brotherhood, and it since has become his primary musical focus. The group has just released its third album called Phosphorescent Harvest on the independent Silver Arrow label. The recording features a more eclectic range of styles than the blues-rock driven Crowes and definitely exudes the spirit of a hippy-gypsy caravan. We caught up with Robinson as he was sitting in traffic on the way into Manhattan during the band's current tour, which stops at The Pressroom on Tuesday, June 24.
