A truly amazing album! The sound quality and stereo effect is brilliant by today's standards, but this recording was made in 1961! After listening to this album, one wonders why Stan didn't stick with the Mellophoniums (they were only there for three years). Despite the inherent intonation problems with the instruments themselves and the "political" problems they caused within the band, the sound that their players make on this album adds a new and unique colour to the fabulous arrangements of Bernstein's music. I am sure that with a bit more work, the Mellophonium could have been refined and become a permanent fixture in many a brass line-up. And let's not forget the rest of the band! Their playing is tight and accurate with brilliant solos from all sections, and the trumpets effortlessly sail up into the stratosphere, and stay there! how do they do that? This album has good sound, imaginative arrangement, fine source material and virtuosity, it should appeal to all lovers of good music.
