Iceburn, known later as the Iceburn Collective, was a musical group formed in 1991 in Salt Lake City, Utah, US, by guitarist/vocalist/composer Gentry Densley, the sole constant member through multiple personnel changes. They were known for their unique style that combined elements of jazz, heavy metal, punk, and classical music. Releasing albums on Revelation Records and Victory Records, Iceburn achieved little mainstream attention, but earned critical praise for their unusual music.
