The three hundred and thirty-first album: #331 Keith Jarrett - The Koln Concert
Showing how small the boundaries can be, this jazz album, a recording of a concert, feels like it could have ended up on the classical list as well. It might be a bit more upbeat and faster than what you'd expect from it, but as a solo piano piece it builds on that same work. It's not, of course, an album that I find myself actively listening to, but there's a bit of spirit in the track that makes it work really well for being this type of piece.
