In 1954 J.J. Johnson and Kai Winding started a fruitful partnership that would run for the next two years, first on Savoy, then Bethlehem and finally ending with a few records for Columbia. The pairing would result in a run of quality albums that brought the two trombonists both critical praise as well as commercial fame. For most of this time they operated as a quintet, with the two trombone front-line joined by piano, bass and drums. Jay & Kai + 6 is rightfully billed to "The Jay and Kai Trombone Octet," as for this outing they are joined by six trombone players in addition to the regular rhythm section. The twelve tunes are arranged by either Johnson or Winding, who manage to not only find space for all the players, but to keep the music exciting and fresh as well.
