Jon spent a great deal of his youth pursuing music. He played in local bands with friends and his cousin, Tony Bongiovi, who owned a fairly renowned recording studio in New York called The Power Station. During that time, he played in a number of bands, and while his grades suffered because of a general lack of interest school, his passion for music knew no bounds. By 16, he was steadily gigging in various local clubs and musical hot spots, and it was in one of these early bands, an outfit called Atlantic City Expressway, where he met keyboardist and future Bon Jovi bandmate, David Bryan.

Like his future superstar bandmate, Richard Stephen "Richie" Sambora was also born in Perth Amboy, New Jersey, though a few years earlier on July 11, 1959. Richie's father, Adam, was a factory foreman, while his mother, Joan, worked as a secretary. Raised Catholic, Richie grew up in Woodbridge, New Jersey, where he started playing guitar at the age of 12, shortly after the untimely passing of one of his musical heroes, Jimi Hendrix. Raised on '60s rock and blues, he was a big fan of the guitar gods of the day, including Hendrix, Eric Clapton, Jeff Beck, Jimmy Page, Johnny Winter and, later, Stevie Ray Vaughan and Joe Perry. Richie was also a big fan of Spanish classical guitar, elements of which would inspire some of his future work.
