Gershwin followed up "Rhapsody in Blue" with "Piano Concerto in F, Rhapsody No. 2" and "An American in Paris," which was inspired by his time in France. He took on social issues with musicals such as, Strike up the Band
, and Of Thee I Sing
, which was a lampoon of American politics that became the first musical to win a Pulitzer Prize for Drama in 1932. Dubose Heyward's novel, Porgy
, was the inspiration for the folk opera Porgy and Bess
, which premiered in 1935 and shocked some with its African American cast. It was a modest success initially, but it eventually became an American standard. "Summertime
" is the show's best-known song and, according to The New York Times
, has been recorded over 25,000 times.
