Requiem, Op.39, for baritone soloist, double choir, string quartet and orchestra. The works published by Weinberger all date from this important period, with the highlight the monumental Requiem, perhaps his most personal and powerful musical statement, an austere elegy to the memory of the Jews who died in World War II, which won the City of Milan and La Scala's first composing competition in 1963 and was premièred at La Scala in 1965. Other important works in the Weinberger catalogue include the String Quintet [premièred by the Alberni Quartet and Bruno Schreker in 1965 and later incorporated into the Requiem,], the Piano Concerto No.1 premièred in 1967 by Yonty Solomon and the Royal Philharmonic Orchestra with Sir Charles Groves and the Piano Sonata No.2 [premièred in 1963 by Neil van Allen].
