From the recording Backing and Jam Tracks for Bass Guitar Vol. 3
This backing track has a simple two measure chord progression, but one of the bass player's jobs is to make a simple song interesting. Keeping the groove in the pocket and adding bass fills at the right time will help. Use the A Minor Pentatonic and Blues scales throughout. 84 BPM.
