Porgy and Bess Orchestral Suite  More than any of Gershwin's songs or larger instrumental creations. the Folk Opera Porgy and Bess may be Gershwin's crowning achievement.
There are songs of the everyday life of the citizens of Catfish Row, magnificent arias like I Loves you Porgy.
Bess you is my woman now, Summertime and I'm On my Way etc.
Robert Farnon brings our the jazz and blues elements in these songs in a way that the original orchestrations by Robert Russell Bennett were unable to do to the same extent. The harmonic sophistication of Farnon is on full dis[lay.
If you have 34 minutes to listen to magnificent American music, that will be musical time well spent.
