Inside Out was a hardcore band from Orange County in 1990. They were comprised of Vic Dicara on guitar, Mark Hayworth on bass and Chris Bratton on drums and a then unknown teenager named Zack de la Rocha.

Inside Out was Zack's first project and he had this to say about it:

"Inside Out was the first band I ever fronted. I channeled all my pain through that band. It was about completely detaching ourselves from society to see ourselves as spirits, and not bowing down to a system that sees you as just another pebble on a beach."

Vic Dicara ended up leaving the band to become a Hare Krishna and at one point played in a band called 108. This was a bit of a trade since Vic's exit from Inside Out killed that band, but 108 provided Zack with Tim Commerford (a.k.a. y.tim.k, Tim Bob, Timmy C.) a person who later ended up in Zack's second band Rage Against the Machine. For true hardcore historians that phrase was to be Inside Out's second album after their first release, No Spiritual Surrender.
