Solo piano arrangement of Liszt's famous symphonic orchestra, “Les préludes“. It was firstly made by his student Karl Klauser, and completely revised in 1863, by Liszt himself. (Liszt actually mentioned that Klauser's arrangement was 'hackneyed'.) The biggest difference between Stradal's arrangement can be heard at 15:40, where Liszt entirely rewrote the recapitulation of the 'Question' section.
