On Gershwin Fantasy, Joshua Bell's Stradivari embraces the lyrical spirit of Gershwin's Porgy and Bess with more success than most vocalists. Accompanied by the London Symphony Orchestra, Bell's violin literally sings through "It Ain't Necessarily So," "Summertime," "I Got Rhythm," and "Love Is Here to Stay," while John Williams (Saving Private Ryan, Schindler's List) serves double duty as conductor and pianist on several tracks. Three Preludes employs the violin and piano transcription by Jascha Heifetz, a longtime Gershwin friend, and features Bell at his jazziest. Even Gershwin himself--well, the recording of a 1926 piano roll of the composer--joins the virtuoso on the swinging "Sweet and Low-Down." --Jason Verlinde
