The inclusion of Liszt "Mephisto Waltz No. 1" is unexpected but it IS great music and Adler gives us a composer's view, emphasizing things that hit him about the piece while in no way attempting to compete with the master pianists that have performed this piece before him.
Beyond that this is music to capture your ears. It may not bring about the raising of the Titanic (and what would?) but it does captivate and enchant.
