Tchaikovsky Symphony No 7 (by Tchaikovsky Foundation with Pyotr Klimov)

Pyotr Ilyich Tchaikovsky's Symphony in E-flat, was commenced after Symphony No. 5, and was intended to be his Sixth Symphony. Tchaikovsky abandoned this work in 1892, only to reuse the first movement in the single-movement Third Piano Concerto, Op. 75, first performed and published after his death in 1895.
A reconstruction of the original symphony from the sketches and various reworkings was accomplished during 1951–1955 by Soviet composer Semyon Bogatyrev, who brought the symphony into finished, fully orchestrated form and issued the score as Tchaikovsky's "Symphony No 7 in E-flat major.
In 2005, a second reconstruction of the symphony, commissioned by the Tchaikovsky Fund, was completed by Russian composer Pyotr Klimov. It had its first public performance at the Tchaikovsky State House-Museum in Klin, near Moscow, by Symphony Orchestra of Russia led by conductor Tomomi Nishimoto 西本智実, on June 5, 2006, as shown in this video.
