Songs were composed by DiCara and Rocha evenly, with some songs having instrumentals and lyrics written by DiCara and some by Rocha while others were collaborations between the two. Just prior to the band's breakup, the music being written was significantly more influenced by hip hop, particularly Run-DMC. They cited influences including Minor Threat, the Bad Brains and Led Zeppelin. Inside Out were a hardcore punk band, in particular, they were a part of its youth crew subculture. In 2006, the track " No Spiritual Surrender" was contributed to the mashup album Threat: Music That Inspired the Movie, where it was remixed by Oktopus from Dälek and dubbed "Ghost in the Machine".
Burning Fight, Deathbed (which Vic later transformed into 108's famous anthem), Undertone (Zack screaming "WAKE UP!" over and over again at the beginning foreshadows the chorus of a slightly more famous song he would write a year later), Empty Days, Redemption, Blind Oppressor, Turn and Face." Remixes According to founder Sunny Singh, the Reading, PA video "includes a number of 's unreleased material. In October 2016, a VHS video of a 1990 Inside Out show in Reading, PA surfaced and was made available online. 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). 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. In early 2013, a high quality version of one of their final shows from May 1991 surfaced and was remastered and made publicly available. Copies of their on-air radio broadcast and various live sets have circulated the tape trading underground and file sharing world for years as popular items. 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. Inside Out performed on California radio station KXLU, showcasing a number of new songs. Vic later started 108, a Krishna-themed hardcore band, and briefly joined Burn, playing guitar in both. They had written material for a second record, to be titled Rage Against the Machine (hence the name for de la Rocha's next band), but the band broke up shortly after their guitarist, Vic DiCara, left the band to become a Hare Krishna monk. Many of their songs' themes are spiritual, but not necessarily religious. They played up and down the West Coast and even toured the East Coast once before their breakup in 1991.
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).
