Psalm 9 is the debut studio album by American doom metal band Trouble, released on March 10, 1984. The album was originally released eponymously and was later renamed to Psalm 9 after the release of the band's fourth studio album, which was their 1990 self-titled release. Along with Saint Vitus' self-titled debut album from the same year, Psalm 9 is considered by many critics to be one of the first doom metal releases. The track "Assassin" was released as a single and included a cover of British rock band Cream's 1967 song "Tales of Brave Ulysses" as a B-side.
