(twice i deleted what i wrote down previous to posting it...oh, well...)
some suggestions:
- nuages gris and bagatelle sans tonalite;
- other pieces from harmonies (avoidinig funerailles);
- something from the annees, such as sposalizio or sonetto 123 (well, take care: the dante sonata is also part of those cycles);
- not my favorite liszt, but something from the soirees.
this is just the top of the iceberg: liszt was one of the most prolific piano composers ever. listen and try something different as well.
best!
