The combination of concept, effort and the right collaborators typically leads to good things no matter what the goal might be. These elements are especially integral to cohesion within a musical ensemble in performance, especially a group built of musicians who haven't previously played together. Pianist/composer James Carney was thinking along these lines when he came up with the idea and chose the musicians for his new recording, Pure Heart. // The sextet that Carney put together is quite an assemblage. For the horns, he recruited his longtime friend and saxophonist Ravi Coltrane, bass clarinetist and alto saxophonist Oscar Noriega, and recent collaborator and trumpeter Stephanie Richards. Bassist Dezron Douglas and drummer Tom Rainey met in their first time ever pairing. In fact, most of these players had never played together before, except Coltrane and Douglas and Noriega and Rainey.
