Hi ronde,
I really enjoyed your Isolde's Liebestod. You played it very well--expressively and with command over its technical challenges. Piano transcriptions can be difficult if the orchestral writing is too literally "translated" into a solo piano piece, making it less than pianistic. Liszt, fortunately, being a virtuoso pianist, had a special talent for capturing the essence of orchestral writing, sound and coloration, while also making it playable on the piano. Even at that, this is still a difficult work to play. Your rendition is fine indeed.
Bravo!
Your own composition was also a pleasure to hear. I braced myself for no melody, atonality or polytonality, disjunctive dissonance, cacophonous percussive sound, minimalism, or whatever else passes for "music" these days. Was I ever surprised and delighted to hear that you had actually composed music rather than noise! Your piece has charm, and even follows formal structure--A-B-A. Hearing it just once, it sounds rather waltz-like. There are some very interesting harmonic modulations, and some beautiful short cadenzas too. The style is quite Neo-Romantic and this piece was like a breath of fresh air. Obviously your audience greatly appreciated it as well. Bravo!
