Buy a used copy for a modest sum and you have a seat at a live performence of arguably the greatest ensemble to perform this opera. The singing is much better than the erratic quality that spoils many live performences and there are less extraneous noises thab usual. Di Stefano is in much richer voice here than in later years although Bastianini's voice is not as sonorous as on subsequent stereo recordings. The great appeal of the recording is having Callas together with such perfect exponents of the leading roles. However a live recording is simply not the medium to appreciate the quality of these voices which was confirmed when I next listened to a studio recording of an other opera which was several years older but where the voices are perfectly preserved. Nor am I convinced that a live performence provides any superior exposition of the drama and for listening pleasure I would always choose studio sound. I would still recommend this recording for anyone interested in the greatest performences and voices of all time.
