From the recording Backing and Jam Tracks for Bass Guitar Vol. 8
This backing track consists of an important chord progression that every bass player must know. The Minor I chord followed by the bIIV, bIV, and the V7 are used in countless songs. For an extra challenge when taking a bass solo, try using the A Harmonic Minor scale over the E7 (V7) chord. That will really bring out the chord tones specific to the V chord. 82 BPM.
