Derrick Leon Green (born January 20, 1971) is an American musician best known as the vocalist of Brazilian heavy metal band Sepultura.

From an early age, Green wished to travel and live outside the United States; he went to Berlin for a time before moving from New York to São Paulo.

The band consisted of guitarist Charlie Garriga (CIV), bassist Frank Cavanagh (Prong and Filter) and drummer Mark Konopka.

Once back from the tour in Europe, Green and Garriga decided that they wanted to move to New York City.

They recorded a three-song demo with the help of Schreifels, the direction was much heavier with influences of metal and heavy rock.

In 1996, Green would start to play guitar and sing with Sara Cox, they would then form the band Alpha Jerk.

They later recruited drummer Luke Abby (Warzone, Gorilla Biscuits), who was then replaced by Nick Heller (Sweet Diesel).

Allmusic.com gave the album 3 stars out of 5 and said, "As Green scrapes the lining of his vocal chords through the brash, impassioned tracks, he's singing about more than just 'one tribe, Sepulnation'; he's suggesting something bigger, something worth shouting about and fighting for".

The EP was exclusively released in Brazil and Japan, but then the band was picked up by record label SPV and Revolusongs was later included as a bonus disc on the digipak edition of Roorback, the next full-length studio album with Green.

Allmusic gave the album 4 stars out of 5 and said, "if there are still any lingering doubts about the Green/Sepultura match, 2003's excellent Roorback should put them to rest for good.

Allmusic gave the album 3.5 stars out of 5 and said that, "Overall, Dante XXI is easily one of Sepultura's strongest releases to feature Green on vocals".

[6] On July 6, 2010, it was announced that Sepultura have signed a deal with Nuclear Blast Records, and will release their first album Kairos for the label in 2011.

Roy Z (Judas Priest, Halford, Iron Maiden's Bruce Dickinson, Helloween) was the producer for the new album.

[7] CD Universe said that "Musica Diablo's extreme fast thrash metal, with the characteristic Brazilian style and a strong root into the 1980s veterans made them unique, and the need of recording a proper album was eminent.

The result is a killer, blast-in-your-face album with 11 songs of sheer violence and pure Brazilian Thrash Metal!".

[9] Green was a guest vocalist on a few CDs including Biohazard's Uncivilization and the soundtrack of the Brazilian movie Lisbela e o Prisioneiro.

Green appeared with Sepultura in a successful ad campaign for Volkswagen that aired nationally throughout Brazil in 2008.

[10] This Volkswagen TV spot shows Sepultura playing bossa nova, the opposite of its Heavy Metal style, to say that "you never saw something like this, as you never saw a car like the new Voyage".

Green is working on a three volume book set of his photography and writings due to be released in late 2011/2012.

So for me, my religion is this planet and having that connection and trying my best to learn to deal with it.Green speaks fluent Portuguese with a noticeable American accent.
