I'd like also to recommend:Bush-Stevenson: The Minstrel's Lay (from Wat Tyler)Berg-Stevenson: Wiegenlied (from Wozzeck)Britten-Stevenson: Peter Grimes Fantasy.I'd recommend more contemporary opera transcriptions if I actually knew any! Ronald Stevenson is one of very, very few people doing this kind of thing since, well, about 1920, really.
There are probably about 10,000 to choose from, so i would ask if there are any particular arias or sections of an opera that you would most like to play.Thal
