Noted for his large-scale orchestral compositions, Matthews is also a prolific arranger of other composer's music, including works by Berlioz, Britten, Dowland, Mahler, Purcell and Schubert.[1] Other arrangements include orchestrations of all Debussy's 24 Préludes, both books of Debussy's Images, and two movements—Oiseaux tristes and La vallée des cloches—from Ravel's Miroirs.
