Read her biographical sketch here.
George Gershwin wrote over 1,000 songs, but much of his classical piano music - as he originally wrote it - was lost since the 1920s. The piano pieces that were available were heavily edited, truncated or incomplete - UNTIL NOW.
Embarking on a historical musical "dig", Dr. Alicia Zizzo, one of America's most eminent classical pianists and scholars, discovered and restored Gershwin's classical piano music from his own hand-written fragments, sketches and original manuscripts.
A find for pianists everywhere, Dr. Zizzo's Alfred Publications (http://www.alfred.com/alfredweb/front/SearchResult.aspx?keywords=Zizzo) of new editions of Rhapsody in Blue (based entirely on his own manuscript), The Complete Gershwin Preludes (all seven fully restored), a piano suite from Shall We Dance, The I Got Rhythm Variations for piano solo, Lullaby and other unpublished manuscripts for solo-piano are now available at all fine music stores or through SheetMusicPlus.com and The Sheet Music Store.
Dr. Zizzo's internationally acclaimed performances of these works and the Concerto in F, as well as Seven Miniatures in Gershwin's Hand were recorded by Carlton Classics on Gershwin Rediscovered, Volumes I and II. Her solo piano performances have now been reissued on the Musicians Showcase Recordings Classics label George Gershwin, The Original Manuscripts (http://www.msrcd.com/1127/1127.html).
