Keith Richards is the heart of the Rolling Stones and, besides being the architect of their sound, defined by some of the best riffs in history. If in other bands one follows the drummer - in the Stones, according to Charlie Watts and Ronnie Wood, one follows the guitar of Keith Richards. ‘Keef’ has always placed a well executed riff before a long solo, and created his own style while he does it. This is thanks to his special tunings and how the riff is adapted - and how he has adapted, and along with him the band, to them. These 10 riffs form a part of the history of rock & roll.
