The Piano Concerto, one of Klenau's last works, was composed in 1944. The concerto, in three movements, exemplifies what Klenau called his 'key defined twelve-tone music'. Like his symphonies nos. 8 and 9 it was discovered among Klenau's manuscripts more than half a century after the composer's death and is published here for the first time.

The concerto is published by the Danish Centre for Music Publication of the Royal Library in cooperation with Edition·S – music¬sound¬art.
