Ann Hell was a one man's band formed by Angel Ortega (vocals, keyboards, guitars, bass and noises) plus several sporadic collaborators, specially for on-stage live performances. First works began on 1988 (shortly after the Kaplan band was disbanded) and ended with an official closing in 2001. Ann Hell's music drifts among the industrial, gothic, darkwave, techno, electronic, new age and experimental genres.
