Brilliant dirty blues rock from the other invading Brits, the dark undertones of this recording make the Stones feel like the anti -Beatles; but here they are ploughing their own furrough, upsetting the neighbours, upsetting women and causing all kinds of chaos. Under my Thumb is the highlight - Sinister and unsettling. The experimentation with a variety of instruments adds flavour and the drumming of Charlie Watts (RIP) is exemplary.
