It's good to be chill sometimes, and this backing track is just that. But that doesn't mean you can relax and lose the groove. Even at this slow shuffle, you need to keep an intense energy level and place every note in it's proper place with the drums. When taking a bass solo, use this relaxed backing track to help you develop a very lyrical solo. Try singing along with your solo to achieve a more natural phrasing too. 54 BPM.
