This disc has gone through several incarnations since its' original release by RCA, but it was and is a demonstration-quality production. I bought it primarily for the Mussorgsky and Dukas, but all performances are first-rate. As to Night on Bald Mountain and the Sorcerer's Apprentice, the tempos are well-chosen (some performances are just too deliberate) and the orchestra plays with real commitment. There are other versions of these pieces which one might judge the sonic equal of these (Lopez-Cobos and Kunzel on Telarc and Oue on Reference come to mind) but they lack the visceral excitement of these performances. A real sonic treat!
