Hi martle,
Well, as you predicted, here I am with some suggestions (of course, some by Liszt!):
Liszt - Reminiscences of Lucia di Lammermoor (S398 - full of runs, trills and swapping of the hands)
Liszt - The transcription of Tschekkenmarsch from Russlan und Ludmilla (S407, use version 2 as it's better - it's got some very beautiful sections interspursed with loud bits - it's actually my favourite Liszt transcription)
Liszt - Ernani - Paraphrase de Concert (S432 - has some amazing arpeggios in the right hand which sound incredible)
Liszt - Any of the Schubert song transcriptions
Liszt - Fantasy on Reinzi (S439 - a great piece, not often recorded and really, really powerful!)
Liszt - Two Transcriptions from Raff's King Alfred (S421 nos.1 and 2 - the first is charming and the second, of the march is full of runs)
Liszt - Any of the Beethoven Symphony transcriptions
Liszt - any of the Berlioz transcriptions (especially the Benediction et Sermet from Benvenuto Cellini S396)
Alkan - Transcription of Mozart's Andante from the 8th quartet (K464)
Thalberg - Paraphrase on Home, Sweet, Home
Gottschalk - Paraphrase on Il Travatore
Tausig - Fantasy on themes from Halka, Op.2
Godowsky - Passacaglia and Fugue on Schubert's Unfinished Symphony
and finally my own paraphrase on Le Chasseur Maudit by Cesar FranckHope this helps!
