Premiered 1968 in Houston, Previn later withdrew this work and wrote another Cello Concerto (as he told me he would during a 1994 interview)…

… however, what is now the ‘first’ Cello Concerto made a big impression on me, and it still does at least four decades later, and in that same Radio 3 broadcast too (link below) – Julian Lloyd Webber with the BBC Scottish Symphony Orchestra conducted by Christopher Adey, circa early-1970s. Apologies though to the composer for sharing music he became dissatisfied with.
