The Subvariants

Take a mixing bowl add Country-Blues-jazz and Rock N Roll spin it around a bit. Add Bob Dylan, The Band, and the Grateful Dead.
Spin it around a little more sprinkle with good ol' old school Motown and Chess releases.
Throw it in a heated jam room with some vintage recording equipment. Let simmer on just the right volume for a just the right time.
What ya get is a great new recipe using the tried and true method since the first time Chuck Berry strummed a six string.
