Anyone who has even the vaguest notion of rock 'n' roll knows that Clapton helped usher in the revolution. The songs "I Shot the Sheriff," "Cocaine," "Layla," "My Father's Eyes," and "Tears in Heaven" ring a bell? How about the bands Cream and The Yardbirds? For as long as rock has been synonymous with roll, Eric Clapton has been considered one of the world's best guitarists, if not the best.  Eric Clapton has been at the top of his game for 30 years. What isn't debatable is his popularity. Eric Clapton is, without question, the world's most famous guitarist. Ask any 10 people to name the first guitarist that comes to mind, and they might say Jimi Hendrix or Jimmy Page, but more often than not, Eric Clapton's name will come up.
