Mario Castelnuovo-Tedesco (1895-1968) may still be regarded primarily as a composer for guitar, best known through his working partnership with Andres Segovia, but Brilliant Classics has illuminated other sides to this prolific musician through first recordings and modern rediscoveries of his piano music (BC94811) and his songs, most notably his settings of Shakespeare (BC95548).

In the same tradition of the operatic fantasy is a paraphrase of Rossini's 'Largo al factotum'; like the two deft miniatures from a series of Greetings Cards Op.170, the paraphrase was issued in print, whereas most of the five-movement Donizetti fantasy remains unpublished. So does the Suite 508 for viola and piano, composed in 1960. With typi
