I don't know whether these are definitive performances of Gershwin's orchestral music, but if they're not then they should be. Previn does a marvellous job as a conductor and soloist who has a great affinity and compassion for Gershwin's music. Indeed, Previn is as much at home playing jazz music as he is conducting Rachmaninov. These are warm, no nonsense readings of Gershwin's music that lack the flamboyance of Bernstein's interpretations with the New York Philharmonic and Los Angeles Philharmonic. Previn produces a warm, vibrant sound from the Pittsburgh Symphony Orchestra. Once again Philips has excelled in producing a well-balanced digital recording. If you're a fan of Gershwin or 20th Century Classical Music (or both) then this splendid recording belongs in your CD collection.
