Slow, melodic, melancholic piano music recommendations?

Question

What are your recommendations for slow, melodic, melancholic piano pieces for listening (a list would be nice), preferably without vocals (unless you insist).

Perhaps something similar to the one (in the flash game):

Try: Olivier Z'Berg

I found this Pianist on Bandcamp.  He sounds exactly what you're looking for.  Slow, nostalgic, melodic, piano only, no vocals.  He released an album called Nostalgia which features mostly melancholic piano only music.  It's beautiful!!!
