Recently, a thread concerning Williamson briefly flourished.  Another CD
I've remembered which may be of interest contains his Concerto for Two
Pianos and Strings, Peter Sculthorpe's Piano Concerto and Ross Edwards'
Piano Concerto (ABC Classics 426483-2), published 1990 but still, I
believe, available, although I'm not sure whether they still have a US
distributor.
