Lambert was most productive in his later years. He progressed most rapidly after taking the music director post at the Old Vic, where he worked with noted musicians of the period, such as
Franco Zeffirelli. He composed music for a range of productions, but also commissioned music from other composers such as
Thea Musgrave and
Michael Tippett (whose music for The Tempest, 1962, was one of the most striking products of this era). Possibly Lambert's most imposing composition during his Old Vic period was his
Organ Mass, composed in a five-year stretch (1964-1968). After that he produced happier, more direct music, such as
Formations and Transformations (1973), and an opera,
Family Affairs, which premiered at the 1988 Brighton Festival. Lambert's later works include a choral work,
Scale (1988), and string quartets. His
Second String Quartet (1986) revealed a more intimate side. The most ambitious project was the cycle
Sea-Change (1978–94), five contrasting works for ensemble and electronics. ==References==
