CD. Mono. Although it has been superceded by the remastered more extensively researched and longer running Live at Carnegie Hall: 1938 Complete this two-CD set issued in 1987 is still very worthwhile to the casual listener and it has virtues that the reissue lacks. Mastered from a triple-LP set that had been cleaned up and edited at the time of release in the early- 50s it is easy on the ear as far as sound quality with none of the clicks and pops that intrude onto the remastered version. It is as valid a document of a concert as any live album ever release and it has about 90 percent of the music that is on the remastering and what music! -- the versions of Don t Be That Way Sing Sing Sing and One O Clock Jump alone are priceless (and arguably definitive in the case of the first two) and they represent only a fraction of what s here. Thus this set is not to be passed over especially at the right price for anyone who isn t an absolute Goodman fanatic. ~ Bruce Eder Rovi
