Pierre-Yves Plat is a french pianist, who, in my sense, is a really good interpreter. In the album below, he gives his own rendition of several classical pieces.
You see, in my opinion, when a musician or singer interprets a famous song, more often than not, they try to mimic the original performer, and the result is not interesting. But sometimes, they try and give a bit of their own personality in their rendition, and the results enhances the original song. Or at least bring something new. For instance, Billy Paul's version of original song.
Here one of my favorite is Pierre-Yves Plat's version of Liszt's Liebestraum (track 7), which is one of my favorite piano piece.
