Agent Steel is an American speed metal band from Los Angeles, California that was formed in 1984 by singer John Cyriis (birth name disputed, possibly João Campos or Jean Pierre), and drummer Chuck Profus. The band released two full length albums, and one EP before disbanding in 1988. They were most notable for John Cyriis's high-pitched vocals, catchy songs, melodic riffs, and fast tempos mixed in with their unusual (in heavy metal) UFOs, and differential anthropology -as the band's song/lyrical themes. The band reformed in 1999 and has released three full length albums since.
