This LP, put out to celebrate the 20th anniversary of the International Association of Jazz Record Collectors (IAJRC), has 11 performances taken from previous conventions of the group. Although several veteran greats are heard from, all of the music (except for two titles that were recorded by Jack Towers) were taped by members of the audience on their own portable recorder. The technical quality is therefore erratic and there is plenty of crowd noise. Pity, for such musicians as trumpeters Charlie Gaines, Jabbo Smith (taking interesting if erratic solos in 1974 and 1976), Jimmy Maxwell and Tom Pletcher, pianists Norma Teagarden, Frank Froeba, Tut Soper and Jim Dapogny, tenorman Flip Phillips (in excellent form on an uptempo "Jumpin' at the Woodside"), trombonist Spiegel Willcox, guitarist Marty Grosz and vocalist Sippie Wallace (singing "Mighty Tight Women") are heard from. But this album is only for a very limited audience despite its historic value.
