Wikipedia : This day (August 25, 1979), in Los Angeles, died Stan Kenton, a conductor, pianist, composer and arranger.
Stan Kenton @allmusic : Kenton’s last successful experiment was his mellophonium band of 1960-1963. Despite the difficulties in keeping the four mellophoniums (which formed their own separate section) in tune, this particular Kenton orchestra had its exciting moments.
@allmusic : He led a succession of highly original bands that often emphasized emotion, power, and advanced harmonies over swing, and this upset listeners who felt that all big bands should aim to sound like Count Basie. Kenton always had a different vision.
@last.fm : Translated into the Kenton idiom, however, the Latin rhythms might be scored for a full panoply of percussion instruments: tympani, bongos, conga, timbales, claves, and maracas. This component of Kenton’s work may be heard on the 1947 recording “Machito” and on the album Cuban Fire,
