Bob Dylan was born as Robert Allen Zimmerman in 1941, in Duluth, Minnesota, US. Originally he was an acoustic folk singer, but in the sixties started to experiment with electric guitars, causing a bit of a riff in the folk singing community. He's contributed to many artists' songs and has been covered by many, too (All Along the Watchtower covered by Jimi Hendrix being a famous example, Mr Tambourine Man covered by The Byrds being another).
His songs include The Times They Are a-Changin', All Along the Watchtower, Blowin' in the Wind, Like a Rolling stone, Mr Tambourine Man, Lay Lady Lay, Knocking on Heaven's Door, Must Be Santa, Just Like a Woman, House of the Rising Sun, Highway 61, The Wheel's on Fire, Desolation Row, Queen Jane Approximately, Maggie's Farm, and many, many others.
