Both recorded in the 50's. Both groups call themselves Dixieland. Both have fine musicians. One is super corny. The other is musical.
Corny gets you on the Sullivan show. Musicality gets you a recording gig in Northfield, MN.
Regarding that Boswell album: I bought it after the glowing review mentioned earlier and was very disappointed. The same zeitgeist that favored the Dukes of Dixieland must have pervaded the production of that record. And I think it was probably difficult for the musicians to collectively forget 30 years of musical developments since the glory days of the 20's.
