I haven’t yet reached the shores of Sviridov (also spellt Swiridow on some CDs), apparently a composer mainly of choral music. The only piece of his that I’ve heard and reviewed is the not very significant Romance for two trombones and piano, on Etcetera KTC 1284, part of their 3-CD set of works performed by the Dutch New Trombone Collective, KTC 1355.
