His music is classical, or the new sub-genre, classical pop. If you like piano music, some with more of an upbeat tempo or the very classic yet somehow new, like songs like Homeward Bound or Ave Maria, even if you are a fan of Led Zeppelin (he did an arrangement of Kashmir), I promise you will enjoy this album.
He has a song that is called Butterflies and Hurricanes. The song is amazing, but the idea of a butterfly in a hurricane I think is a poem or story just waiting to happen (hint, hint, Erin).
Give yourself a treat, especially if you are feeling half as frazzled as I have been lately, and give William Joseph a listen. You will be so happy you did. You can preview some of his tracks here.
If you were wondering, the one I am working on is Piano Fantasy.
