 That was the Mephisto Waltz No. 2 by Franz Liszt, as recorded by Leif-Owe Ansnes, dating from 1881, making that quite a late work of Liszt. And he went on to write two more, which we're going to hear in just a moment. I want to point it out, though, that that's rather unusual because, as you probably know, a waltz is in triple meter, three beats to the bar.
