Among the giants of Jazz was Gerry Mulligan, most noted for his saxophone and as a composer and arranger. He joined forces with Miles Davis in the late 40’s as an arranger for many of the tracks on Davis’ “Birth of Cool.” Mulligan would go on to collaborate with other Jazz greats like Stan Kenton and Chet Baker. Among his own best received albums was “Mainstream of Jazz.” Released on Emacy Records in 1955, a copy is worth up to $150.00 today.
