Scott Hamilton is an American jazz tenor saxophonist associated with swing and straight-ahead jazz. His eldest son, Shō Īmura, is the vocalist of the Japanese rock band Okamoto's.

Straight-ahead jazz is a genre of jazz that developed in the 1960s, with roots in the prior two decades. It omits the rock music and free jazz influences that began to appear in jazz during this period, instead preferring acoustic instruments, conventional piano comping, walking bass patterns, and swing- and bop-based drum rhythms.
