Original vs. revised

Sergei Rachmaninoff's Second and Third Piano Concertos are repertory staples. His First and Fourth Concertos were not successful at their original premiers, but were heavily revised later and were replayed with some success. Near the end of his career, Rachmaninoff recorded both of them with the Philadelphia Orchestra, conducted by Eugene Ormandy.

On this week's Classics of the Phonograph, Saturday at 11 am on WILL-FM, we will hear portions of those recordings.
