Solitude Aeturnus is an American epic doom metal band from Arlington, Texas. Founded by John Perez in early 1987, the original lineup consisted of Perez on guitar, vocalist Kristoff Gabehart, guitarist Tom Martinez, drummer Brad Kane, and Chris Hardin on bass. The name Solitude was chosen to pay homage to the bands Black Sabbath and Candlemass, both of whom had songs bearing the name "Solitude". Solitude Aeturnus released their debut album "Into the Depths of Sorrow" in 1991 with John Perez and Edgar Rivera on guitars, Robert Lowe on vocals, Lyle Steadham on bass and John Covington on drums. Solitude Aeturnus played with Candlemass in Texas in 1991. Their second and most progressive album, "Beyond the Crimson Horizon", was released in 1992. "Through the Darkest Hour", the band's landmark album, was released in 1994. "Downfall", the band's fourth studio album, was released in 1996. "Adagio", released two years later in 1998, featured Steve Moseley on bass, who replaced Lyle Steadham. Lyle Steadham was the main lyricist of the band until then.
