Finally my chance to shine and show I’m more than just muscles! Just kidding I don’t play the piano but Yann Tiersen does. You’ve most likely already heard some of his music. Probably in the movie: ‘Amelie’, or his song: ‘Comptine d’un autre ete : L’apres midi’ which is used as a backdrop in many short films and clips.

Edit: As I read your question again, I get the feeling you don’t want to just listen to the music, but learn how to play it. Listening to the song I realize you’re not looking for anything like Yann Tiersen (but I’m not removing it, for he sir, is awesome!). So without further ado, here is my second answer:

Randy Newman and Ben Folds are well known for their piano work, they’ve got some uptempo repertoire and some slow songs (especially Ben tends to get a bit dramatic).
Randy Newman -> Louisiana 1927, Sail away, You’ve Got A Friend In Me but you probably know him from his song: Short people or his song: It’s a jungle out there (theme from Monk the tv series).
Ben Folds -> Bastard, Annie waits, Not the same, and here is a list of songs he did with the Western Australian Orchestra (ASO).
Who could forget Elton John (his early work from the 70’s), but I’ll let you find their own songs. Also try using Last.fm for exploring new or similar music. This link will show you what they think are artists similar to Larry Goldings.
