Founded in 2000 by songwriter and vocalist William Wilson, Legion Within's distinctive sound quickly established them among the best of their genre. Having their feet planted firmly in both romantic darkwave and classic industrial, they have shared the stage with compatriots on Projekt Records including Black Tape for a Blue Girl, Voltaire, and Audra, as well as Collide.

Debut album, Ayumi, met critical acclaim including "If you've been longing for gothic rock in the classic style, Legion Within will satisfy your craving" (Industrial Nation) and "[Legion Within] create beautiful gothic atmospheres with an airy ethereal feel while still being grounded by the depth of a live band" (Outburn).

The much anticipated follow-up album AEONS built upon their "old world ambience" with the creepy carnival sound of "Dream Carny" and industrial weight of KMFDM's "Cover Me" remix.

In creating their third release, The Empty Men, Legion Within partnered with the production gurus of KMFDM; Jules Hodgson, Steve White and Sascha Konietzko. The Empty Men expresses bleak political sentiment and pulsing industrial beats ("Fascisti", "Rise") while retaining their dark romantic roots ("Wrath of the Empty Men", "She Chides", "Led Astray").

For their new album, Mouth Of Madness Legion Within formalized their connection with KMFDM, releasing the CD on KMFDM Records through the KMFDM Store. Once again they teamed with Jules Hodgson for production and Sascha K. for a remix to concoct a developed and mature album. Filled with the band's distinctive and accomplished brand of dark rock and flavored with what singer William Wilson calls, “Courageous Nihilism", Mouth Of Madness is both moving and entertaining.
