The Swedish Chamber Orchestra and Thomas Dausgaard here perform two works by Pyotr Tchaikovsky as part of their “Opening Doors” series. The series presents large-scale Romantic symphonic works with the clarity that a chamber orchestra can offer. Previous recordings include a full cycle of Schumann’s symphonies, Dvořák’s ‘New World Symphony’, and Symphony No. 2 by Bruckner. The works here come from either end of Tchaikovsky’s career and are linked by the tragedy apparent in their endings.
