The Czerny concerto is an time favourite of mine, ever since finding it on an obscure American LP back in the 1970's! I was also fortunate enough to attend a live performance given by Harvey Dagul and his wife a few years later. Yes, there are torrents of notes, but it is extremely well constructed for the medium. It can also be performed without orchestra for anyone interested, and it is great fun to play. It also has its more tender moments - try the development section in the first movement, which starts in the key of E minor, before some surprising sequential modulations which Czerny was most adept at! Altogether a most enjoyable work both to listen to and also to perform! It would surely bring the house down at the Proms!
