Piano Concerto No. 4

'''Piano-Concerto Nr. 4''' (Wolf Castle) is a classical piano concerto written by Emmanuel Berger. He published the music in 1834 and gave concerts in the fall of that year. The piece influenced him to write his novel Wolf Castle, and is undoubtedly his most famous work

The piece is split into three parts:


 * 1) Andante molto mosso
 * 2) Marcia moderato
 * 3) Allegretto con brio

History
Berger revised his Piano concerto in 1835, which is the version most performed. He had hoped to have French pianist Henri Bertini, who he admired, to debut the piece, but he was unwilling to come to Brunant and Berger played it himself.

In 1977 a disco version of the piece by Libertan disco duo Macros became a hit in Brunant.
