REUTERS/ COLUMBIA RECORDS/ PARAMOUNT HOME ENTERTAINMENT - Bob Dylan is one of the most celebrated and influential musicians of modern times.

And on May 24 Dylan will celebrate his 70th birthday.

Dylan first shoot to fame in the 1960s and 70s by epitomizing the anti-war sentiment of American youth and becoming the unofficial spokesman of that generation.

During his career, Dylan's style has switched from folk to rock to country - and even once flirted with a 'heavy metal' sound.

Though he's well into his pension years, the American singer and songwriter still travels and performs more than most artists, playing roughly 100 dates a year.

His tour has been dubbed 'The Never Ending Tour' as it has rarely stopped since it began in 1988.
