Way to go Andrew! Well that is my contribution to the current celebration of Liszt: to hopefully increase the knowledge of those who have no notion of how modern his late-thinking was regarding harmony. This is the second page of a two-page work, that most will find most foreign to the language of Liszt.
I think the average listener would have their expectations confounded by much of late Liszt: the period where he was trying to "throw his lance into the future". He influenced the Second Viennese School; indeed I believe Verklarte Nacht quotes from the sonata. Unstern! Sinistre, disastro is a fascinating piece and I think the piano/cello version of La lugubre gondola is absolutely beautiful.
