There is a possibility that Panos Trochopoulos will record the 2nd Piano Concerto for Cameo with the Malta Symphony Orchestra in November. The conductor will be Leslie Howard (the Liszt specialist). A possible couplng is the ballet "Aucassin et Nicolette", which was successfully toured for more than one season by the Sadlers Wells ballet, but this has yet to be determined.
Having seen the 2-piano version of Holbrooke's "3rd Piano Concerto" - more correctly known as Symphony No. 8, Op. 112 - 'Dance Symphony', but in reality a PC - I can only deeply regret the absence of a Full Orchestral Score for this work.
