I have, Peter. I bought the MDG disk of his songs (advertised on the website you mention) when it was released, about 6 or 7 years ago I think. I read the score of the Piano Cincerto at the British Library and Hyperion were thinking of recording it, coupled with the Bronsart PC, but it looks as if CPO will beat them to it. The symphony contains some attractive music and is beautifully (if conservatively) scored), but it is a little too long for its material. There is a very good Piano Trio and some other chamber pieces, but the concerto and symphony are his major orchestral works.
