This album's been out for a few years now, but is one of the few solo bass records that I come back to time and time again to listen to.
As I've said before, I don't like most solo bass playing. Jeff's a massive exception to that rule. His music is amazing.
He also did an amazing podcast about the making of the album, and continues to blog smart musical things at beautiful-bass.com
Here's the album, listen, then download it, it's amazing:
