The most famous and probably greatest jazz baritonist of all time, Gerry Mulligan was a giant. A flexible soloist who was always ready to jam with anyone from Dixielanders to the most advanced boppers, Mulligan brought a somewhat revolutionary light sound to his potentially awkward and brutal horn and played with the speed and dexterity of an altoist.
Mulligan started on the piano before learning clarinet and the various saxophones. His initial reputation was as an arranger. In 1944 he wrote charts for Johnny Warrington's radio band and soon was making contributions to the books of Tommy Tucker and George Paxton. He moved to New York in 1946 and joined Gene Krupa's Orchestra as a staff arranger; his most notable chart was "Disc Jockey Jump." The rare times he played with Krupa's band was on alto and the same situation existed when he was with Claude Thornhill in 1948.
