Beautifully played and sung, this is one of the two best Porgy's out there, at least if we're talking about the complete opera. What happens when Gershwin is played by world-beating musicians will probably change your perception of the composer. Most of the singers do well, with a few hiccups along the way. Willard White as Porgy has a big, rich baritone. Leona Mitchell as Bess and Florence Quivar as Serena deliver some strong singing. However, all three don't do much dramatically beyond the standard (and quite acceptable) notions of Operatic Acting. McHenry Boatwright's Crown is probably classic. Maria (Barbara Conrad) has problems negotiating her speaking voice into some form of agreement with her singing one. On the other hand, she delivers a great "I hates your strutting style" to Sportin' Life. Francois Clemmons as Sportin' Life gives a performance of real style. Cab Calloway, of course, buries him, but then again Calloway blows away everybody. The actors in the white speaking parts embarrass themselves, although not as badly as in the Harnoncourt recording.
The good news is that the opera is the complete Boston premiere version, rather than the New York Broadway version Gershwin trimmed in the interests of performance practicality. Maazel gets some frankly unearthly playing from the Cleveland Orchestra. But he does have problems handling Gershwin's transitions, and the dramatic pace drags here and there. Still, as I've said, one of the two best versions out there.
