Alan Yentob embarks on a three-part personal journey to discover how the guitar became the world's favourite musical instrument. Beginning with the rise of the acoustic guitar, the series takes him from an ancient Middle Eastern ancestor of the lute, to the iconic guitars draped round the necks of Bill Hailey and Elvis Presley and beyond.

As the guitar turns electric, music is changed for ever. The world's first electric guitar had nothing to do with jazz or blues, but Hawaiian-style music and was known as the 'frying pan'. Yentob continues his investigation from the blues of the Mississippi to the guitar wars of the 1950s, when the Fender Stratocaster and the Gibson Les Paul were battling for supremacy.

In the final programme of the series the guitarists talk about how they find their own sound, and how the guitar has changed their lives. Since its invention, the electric guitar has unleashed a seemingly inexhaustible sonic invention among guitarists.

Alan Yentob explores the work of artists whose primary medium is light. On his trip down the light fantastic, Alan encounters material from outer space, solid light sculptures, paintings made by the sun and an extinct volcano that has been turned into a temple of perception by the legendary American artist James Turrell.
