Piano music suggestions please (read details)?

I play piano and i wanted some suggestions on artists who are really good singers and piano players (preferably male) that make really good music. To give you some idea of the kind of music i like some of my favorite artists/bands include ben folds, dave matthews band, better than ezra, OAR, john mayer, damien rice, the beatles, glen hansard and market irglova, jack johnson. I have a wide variety of taste in music but i hate most of the tops hits like the top songs on itunes and i dont like country, or rap. I like alot, all the way from opera to rock/alternative to clical... any suggestions on artists who are really good singers and piano players that are guys?
