Their albums had a hard-driving rock and roll sound. After the first two albums on independent Slash Records, X signed to Elektra in 1982 to release Under The Big Black Sun. 1983 saw the release of the More Fun In The New World album and the feature-length documentary about the band, The Unheard Music.
Though X recorded some albums without original guitarist Zoom, the band regrouped in the early 1990s to record and are still playing shows as of 2002. Bassist/singer John Doe moved more toward country music in his solo work, starred in the independent film Roadside Prophets with Beastie Boy Adam Horovitz.
