Joe Satriani was born on July 15, 1956 at Westbury (in the state of New York). He played a little on his sister’s guitar. She had played some folk music in high school. He was inspired since he was young by Blues music, the Beatles and the Stones so when he turned 8 he started playing drums, then some piano a bit later. On September 18, 1970 all collapsed around him when he learned that Jimi Hendrix passed away. Joe was only 14 but he decided from this moment to stop everything and dedicate his life to learn the instrument of his idol.
