In the early 1960s Goffredo Petrassi's idiom was almost indistinguishable from that of the Italian avantgarde. Completed in 1964, the Seventh Concerto evolves with mounting tension and a sense of underlying menace. The Eighth Concerto from 1972 was commissioned and premiered by the Chicago Symphony Orchestra. It is a substantial piece of outright virtuosity, with dissonance, trenchant dialogues and a fraught atmosphere. The much earlier Sonata da camera for harpsichord and ten instruments finds Petrassi poised between neo-Classicism and a more modernist direction. This is the third and final volume of Petrassi's complete Concertos for Orchestra on Naxos (Nos. 1-3 are on 8.573702; Nos. 4-6 are on 8.573703).
