I really have a soft place in my heart for his three warner bros. albums, most recently compiled into 2cds as "A Standing Eight" on 32 Jazz. A great eclectic collection of music with great sidemen/women (Hank Jones, Milt Hinton, Trudy Pitts, Charlie Persip, Steve Turre, Percy Heath,Tiny Grimes, Sammy Price, etc). Kirk mainly plays tenor sax with some flute and harmonica. Very little multiple horn playing since a fair amount of this music is post stroke.
I doubt many people think these are his best releases but you certainly have to admire his determination to the end even though he didn't have much left to give. I equate his last album to Ellington's tribute to Billy Stayhorn in that you feel the joy and celebration in the music as well as the sadness and melancholy.
