The Cincinnati Symphony Orchestra will be performing Farrenc's overture no.2 on Feb.28 & Mar.1 2026, with Samuel Lee conducting.
Chamber works by Franz Schmidt (Quintet in A major with clarinet) and Pfitzner (sextet op.55) will be performed in Ulm on 12 July 2026.
That'll start...
15.1.2026, Helsinki, Finland (Musiikkitalo): Korngold's Cello Concerto op. 37.
18.1.2026 (same venue): semi-unsung Dora Pejacevic's Piano Trio op. 29, and Germaine Tailleferre's Piano Trio.
Neat!
I also see listed a performance of Myaskovsky's 6th symphony (https://www.operabase.com/productions/symphony-no6-op23-344275/en) conducted by Alexander Rudin in Moscow on 7 April, a recital ending with Myaskovsky's 2nd piano sonata (https://www.operabase.com/productions/evgeny-kissin-338437/en) in Toronto played by Evgeny Kissin on 22 May, another Kissin program in Paris (unspecified cellist??) with the same composer's 2nd cello sonata (https://www.operabase.com/productions/evgeny-kissin-piano-336416/en) on 28 January . (Ah, I see that operabase starts charging after the first few uses. That's why...)
January 28 2026 in Stuttgart (https://www.staatsoper-stuttgart.de/en/schedule/a-z/3-chamber-music-concert-2025-26/), string trio by Robert Fuchs (in E minor, Op.61 No.1 - miscalled E major because it has an introduction in that key, but nothing else*), Hans Gál clarinet quintet, and Franz Schubert B-flat piano trio.
Same location, April 29 (https://www.staatsoper-stuttgart.de/en/schedule/calendar/6-chamber-music-concert-2025-26/8759/): Gade's piano trio in F, Bloch's violin sonata no.2, and Enescu's octet in C. Neat concert.
*Which makes as much sense as calling Haydn's Symphony No.104 a symphony in "D minor".
