Catfish Row, originally titled Suite from Porgy and Bess, is an orchestral work by George Gershwin based upon music from his famous opera Porgy and Bess. Gershwin completed the work in 1936 and it premiered at the Academy of Music in Philadelphia on January 21 of that year, with Alexander Smallens conducting the Philadelphia Orchestra. Gershwin played the piano part, including the piano solo in the opening moments. This piece preserves some of the darkest and most complex music Gershwin ever wrote.
