Question: Which year witnessed the formation of the performer of Black Tattoo?

full_context: Document 1: The Red & the Black: The Red & the Black is a rock album by the Poway, California band Agent 51, released by Surfdog Records in 2003. It was the band's third album and was named "best punk album" at the 2003 San Diego Music Awards. With it the band distanced themselves from their previous punk rock sound by incorporating much more of an influence of classic rock and heavy metal bands such as AC/DC, Motörhead and Def Leppard. They also distanced themselves from the secret agent mythos they had created for themselves by ceasing to wear matching black suits in concert and by ceasing to write songs dealing with the existence of extraterrestrials and UFOs. The song "Loaded" was originally titled "Fuckin' Loaded" but was changed for printing on the album sleeve. They received airplay on local rock radio station 91X for the song "She's My Heroine." The album was the band's last before their extended hiatus, and they would not reconvene until a reunion show in 2005. Agent 51 have not released any more albums since "The Red & the Black".
Document 2: Comeback (Grinspoon song): "Comeback" is the first single from Grinspoon's sixth album "Six to Midnight". The song gained radio airplay in Australia and had a music video filmed for it. The song peaked at No. 48 on the ARIA Singles Chart.
