"I learned to play the bass, the guitar, and as much of the drums as I could by listening to Pearl Jam": See producer and superfan Andrew Watt performing Alive back when he was a little-known solo artist

Andrew Watt performs during the "Chameleon" New York Premiere Hosted By Mick Rock at The Electric Room on May 29, 2012 in New York Cit.

Even putting aside the fact Andrew Watt went from producing the Rolling Stones' Hackney Diamonds to helming an album by his favourite band Pearl Jam two days later, his journey has been remarkable. 

From solo artist to California Breed guitarist alongside Glenn Hughes and Jason Bonham, then pop session player and super producer for Justin Bieber, Dua Lipa, Post Malone and Ozzy Osbourne with Rick Rubin as a mentor.
