Liszt’s posthumous Piano Concerto in E-flat major was unknown until 1989, when the first edition of the score appeared. Coming soon after the discovery of De profundis, a further revelation was that, in addition to the well-known Piano Concertos in E flat major and A major, Liszt also composed another concerto, the author’s manuscript of which is divided into three parts and can be found in three different archives. Both works, which emerged from Liszt’s estate, were discovered and reconstructed by Jay Rosenblatt, an American Liszt scholar, based on the manuscripts. After studying the autograph, it could be ascertained that the posthumous piano concerto in E flat major was composed in 1839 and was intended for Liszt's first concert tour starting that same year (though he never played it), similar to the versions of the E flat major and the A major piano concertos of that time.
