Darkest Hour (band) Darkest Hour is an American heavy metal band from Washington, D.C., formed in 1995. Though failing to break early in their career, the band has received acclaim for their albums "Undoing Ruin", "Deliver Us", and "The Eternal Return". "Deliver Us" debuted at number 110 on the Billboard album charts, with sales of 6,600, and their more recent effort "The Eternal Return" garnered them an even higher position in the Billboard album charts at number 104. Their latest self-titled effort charted at 102 on the Billboard 200, a peak for the band, and it marked a stylistic shift in the band's discography.
Blood In, Blood Out (Exodus album) Blood In, Blood Out is the tenth studio album by American thrash metal band Exodus. It was released on October 14, 2014 through Nuclear Blast, and is the band's first album with vocalist Steve "Zetro" Souza since 2004's "Tempo of the Damned". The album also saw a reunion with original guitarist Kirk Hammett, who plays the guitar solo on "Salt the Wound". "Blood In, Blood Out" received generally favorable critical reviews, and it entered the "Billboard" 200 at number 38—the band's highest U.S. chart position to date. Exodus promoted the album with its first concert tour with Souza since he left the band in 2004, due to a feud with guitarist Gary Holt.
