Joseph Satriani (born July 15, 1956) is an American rock guitarist, composer, record producer, and songwriter. Early in his career, he worked as a guitar instructor, with many of his former students achieving fame, including Steve Vai, Larry LaLonde, Rick Hunolt, Kirk Hammett, Andy Timmons, Charlie Hunter, Kevin Cadogan, and Alex Skolnick. Satriani went on to have a successful solo music career, starting in the mid-1980s. He is a 15-time Grammy Award nominee and has sold over ten million albums, making him the bestselling instrumental rock guitarist of all time.
In 1988, Satriani was recruited by Mick Jagger as lead guitarist for his first solo tour. Satriani briefly toured with Deep Purple, joining shortly after the second departure of Ritchie Blackmore, in 1993. He has worked with a range of guitarists during the G3 tour, which he founded in 1995. Satriani has been the guitarist for the supergroup Chickenfoot since joining the band in 2008.
