I love the Louis Cottrell album--clarinet, guitar, and bass--it's so refreshing to hear New Orleans jazz from this period without the clunky, non-swinging traditional pianists who mar some otherwise decent recordings.
Herb Hall is as good as Ed Hall, maybe better.
Haven't heard much Jack Maheu, but he plays a very emotional clarinet.
Frank Chace sounded more like Pre-War Pee Wee Russell than Pee Wee did. As I mentioned in this forum once before, Chace was a perfect foil for Jabbo Smith's last great recordings.
