Released for the first time in the West, Sergei Skripka conducts Tchaikovsky"s unfinished Symphony No. 7, reconstructed by Semyon Bogatyryev in the 1950s. In the spring of 1891 Tchaikovsky began to sketch out ideas for a new symphony. In his programme he wrote, "The ultimate essence is Life. The first part is all impulse, passion, confidence, activity... Second part is love; third disappointment; fourth ends dying away."
