by Scott YanowAlthough a recording with Al Porcino's big band was titled The Final Performance, tenor saxophonist Al Cohn made two later recordings before his death in 1988. Keeper of the Flame, his next-to-last album, is a somewhat obscure set recorded in London with "the Jazz Seven." Although none of the sidemen would qualify as household names, they are quite professional and fine bop players. Cohn, who is the main soloist, stretches out on four group originals, "Mood Indigo" and his own "High on You." His tone had deepened through the years and Al Cohn is actually more distinctive on this recording than he had been in the 1950s.
