Also part of the 12 X 5 tune stack are three more tracks that were later included in the Stones' second UK full-length The Rolling Stones No. 2. 12 X 5 is dominated by the Stones' takes on R&B and blues songs. The way in which Mick Jagger, Keith Richards, Charlie Watts, Bill Wyman and Brian Jones interpreted these songs shaped and informed the hard blues/R&B wing of the British Invasion in ensuing years. The Clearly Classic edition is based on the original mono mix.
