On his 13th studio album, the wackily titled Professor Satchifunkilus And The Musterion Of Rock, Joe Satriani does something extraordinary. Actually, he does it repeatedly: amidst all the wham-bam guitar gonz and the 'hey-listen-to-this!' squeals and whoops that never fail to elicit head-shaking awe, he injects heaping doses of humanity into the action. Is this what it means to be a guitar hero in the 21st Century? It is if you're Joe Satriani. In this exclusive MusicRadar podcast, Satriani talks about his early days, the new album and the obstacles he faced in trying to outdo himself yet again.
