This compilation of works by Wooten + Bailey is not to be taken lightly. Once you start practicing their music, you'll enter into the realm of colors, sounds, and landscapes that you never knew your bass had. This may be too difficult for intermediate to advanced players, (I myself included!), but by slow practicing and extreme diligence, you can develop your chops better than any other method books on the market. Geared towards 4 string bass (normal and tenor tuning), as well as 6 string. The accompanying CD really does give you an idea of how the pieces sound. A must for those who like to sweat!
