Of all the Gershwin books out there this one possibly contains the most quality arrangements for the price. It not only contains the full piano solo version of Rhapsody in blue, which takes up over 20 pages, but also his early classics like Swanee, Sweet and Low Down, and Novelette in Fourths. It contains a good chunk of his early piano solo works like I Got Rhythm variations but it also does leave out some of his most famous works like An American in Paris, which is another piece that takes up over 20 pages typically, and his Bessie and Porg songs are left out. Still, for the price it does contain the all famous Rhapsody in Blue in its most popular arrangement style and a lot of his other classics, more than most other Gershwin books.
