Levine's interest in music started at around ten years of age, when he first started playing the guitar. He found music as an outlet for his feelings, stating: "I picked up a guitar and that was it. I fell so madly in love with it, it's all I did". He performed his first professional gig at The Troubadour when he was twelve, but he was so nervous that he played with his back to the audience. Throughout his childhood, he had a wide range of musical influences, including The Beatles, Fleetwood Mac, The Who, Pearl Jam, Soundgarden, Alice in Chains, and Nirvana, and, in high school, Bob Marley, Bill Withers, Al Green, Stevie Wonder, Marvin Gaye, Phish Relix and Michael Jackson. He has also incorporated elements of The Police and Prince into his music. In an interview with Billboard, he explained the diversity of his influences: "I love every single kind of music ... even the most saccharine, sugary pop song can be the greatest thing ever. But so can a 25-minute crazy avant-garde fusion gnarly Herbie Hancock jam from the '70s".
