Please answer my jazz question?

"My Jelly Roll Soul" (alternate take) is a swinging, euphonic number reminiscent of pianist Jelly Roll Morton's Dixieland style. It is 11:25 minutes long, but very similar to "Jelly Roll" from the disc Mingus Ah-Um. The baritone saxophone solo is particularly enjoyable, and exemplifies the well-crafted harmonics. I chose the song because it is probably the best track on this Charles Mingus album, and because of the title, since I am a Jelly Roll fan.
