Lethal was an early Argentinean thrash metal band that was formed back in 1984. The guitarists Charly Guillen and Yankee, bass player Pablo Alvarez, and drummer Miguel Pratto had founded the band using the name Legion. Two singers came and went before Tito Garcia joined. Bienvenidos A Mi Reino (‘Welcome To My Kingdom’) was issued as a cassette only to be issued on CD eight years later. Guillen would leave the band after Maza and die of AIDS. The group was increasingly more hardcore sounding with Lethal 5.0 abandoning metal. The group reappeared in 2004 to commemorate its twentieth anniversary.
