This was mentioned in the Eroica Symphony thread here: https://www.pianostreet.com/smf/index.php?topic=63788.msg677838#msg677838There may have been some confusion in that thread that Alkan did not transcribe the symphony, but the concerto, 1st movement only with his own elaborate cadenza in which he creatively plays tribute to Beethoven's fame. Another attraction besides this cadenza is Alkan's skill in interweaving the solo piano part into the fabric of an orchestral reduction. It may have been thought impossible, but Alkan proves his genius. This was the only performance I gave of this, from a concert in March 2014 which also included the Alkan Concerto for Solo Piano which I shared sometime back. Enjoy listening, but don't trip over the warts!
