Ryan Keberle Double Quartet: Ryan Keberle Double Quartet

Warm and breezy, trombonist Ryan Keberle’s debut release expands the standard quartet with four additional brass pieces, a configuration balancing the rich sense of a large ensemble with the fluid agility of a small band. The disc is upbeat from start to finish, as easygoing originals alternate with crisp, well-mannered arrangements of tunes by the Beatles, Wayne Shorter and Brad Mehldau. Neatly layered horn passages stand out throughout the disc, which is also distinguished by Keberle’s ever-cheerful solos.
