Kenton was a salient figure on the American musical scene and made an indelible mark on the arranged type of big band jazz. Kenton's music evolved with the times throughout the 1960s and 1970s, and although he was no longer considered a contemporary innovator, he promoted jazz and jazz improvisation through his service as an educator. The "Kenton Style" continues to permeate big bands at the high school and collegiate level, and the framework he designed for the "jazz clinic" is still widely in use today.
His music has experienced a resurgence in interest, with later critical "rediscovery" of his music and many reissues of his recordings. An alumni band tours to this day, led by lead trumpeter Mike Vax, which performs not only classic Kenton arrangements, but also new music written and performed in the Kenton style.
Kenton donated his entire library to the music department of North Texas State University (now the University of North Texas), and the Stan Kenton Jazz Recital Hall is named in his honor. His arrangements are now published by Sierra Music Publications.
Kenton continued leading and touring with his big band up to his final performance in August 1978. He suffered a stroke in August 1979. Kenton did not recover and died on August 25, 1979. He was interred in the Westwood Village Memorial Park Cemetery, Los Angeles
