Slash had the ultimate music teacher when he was growing up - legendary Rolling Stones guitarist Ronnie Wood.
The former Guns N' Roses rocker was born and raised in England before moving to the U.S. with his family at the age of 11.
Wood is adamant he was a huge influence on Slash's technical skills, showing him how to play complicated riffs on the guitar - and nowadays Slash returns the favour.
Speaking on Britain's Absolute Classic Rock radio, Wood says, "Slash, I remember him as a kid spying on me when I was playing guitar and I'd teach him little licks, and now I'm learning licks off him, it's really good.
"He's a great guy to play with and he's great at interacting, a good weaver, you know, we can weave, like me and (Bobby) Womack do and me and Keith Richards do. Slash is such a great talent, and he plays in my solo band when I take it out and he's on my new album as well."
