Inside Out existed from August 1988 to roughly fall of 1991, releasing a single 7" EP, No Spiritual Surrender, in 1990, on Revelation Records (later converted to six song CD). They played up and down the West Coast and even toured the East Coast once before their breakup in 1991. They had written material for a second record, to be titled "Rage Against the Machine" (whence the name for de la Rocha's next band came), but the band broke up shortly after their guitarist, Vic DiCara, left the band to become a Hare Krishna monk. Inside Out performed on California radio station KXLU,
showcasing a number of new songs including the song "Rage Against the
Machine", which had become a staple in their recent live sets. The
quality of the recording on the show, while adequate for a radio
broadcast, is not on par with that of the band's EP recording. Copies of
their live radio appearance and various live sets have circulated the
tape trading underground and file sharing world for years as popular
items. In early 2013, a high quality version of one of their final shows
from May 1991 surfaced and was remastered and made publicly available.
Lyrics to the previously unreleased songs "Rage Against the Machine" and
"Darkness of Greed" were deciphered, and together they give new context
to the early beginnings of Rage Against the Machine. 
Some of their songs focus on issues in society and in the USA
(Redemption, Burning Fight) and some are personal to members of the band
(Sacrifice, By a Thread). Many of their songs themes are spiritual, but
not necessarily religious.
