Other major orchestral works include Aura and Biogramma (both 1967) and Quadrivium, for four percussionists and four orchestral groups (premiered at the 1969 Royan Festival). Giuseppe Sinopoli recorded all three of these pieces with the North German Radio Symphony Orchestra in 1979. Maderna's Requiem, composed between 1944 and 1946, was rediscovered and performed in 2009; the American composer Virgil Thomson saw an unfinished version of the score in 1946 and praised it as a masterpiece.
