In 1999, he moved to Finland, and began looking for Piotr Ilyitch Tchaikovsky's legendary "Flute Concerto", of which Rampal had seen a page in the 1960s in the Soviet Union.

He eventually found three pieces of the original composition (one in St. Petersburg, one in Finland, one in Klin) and reconstructed from them the Concertstück for Flute, TH 247, now catalogued as a posthumous work by Tchaikovsky.
