Follow the great arc of music on these early ECM productions, with works for orchestra and improvisers, guitar duo, solo piano, and jazz quartet. Keith Jarrett and conductor-pianist Dennis Russell Davies have been friends and musical comrades for forty years. In the mid-70s the St Paul Chamber Orchestra, under Davies' direction presented Jarrett's chamber music. In the 90s Jarrett recorded the Mozart piano concertos with Davies and the Stuttgarter Kammerorchester. Near the beginning of their association, Jarrett invited Davies to play a composition he had written for solo piano. To listen to Ritual is akin to experiencing the core of a Jarrett solo concert. The interpreter may be different, but the lyrical expression is remarkably consistent. As Dennis Russell l Davies says: "Those who know Keith will hear him in this music. It couldn't have been written by anyone else. "
