In February 2012, Kory Clarke left Trouble. Kyle Thomas, who was with the band from 1997 to 2000, took his place. Also in February 2012, two original members of Trouble — vocalist Eric Wagner and drummer Jeff Olson — joined forces with the band's longtime bassist Ron Holzner in a new heavy rock/doom metal act called The Skull. According to a statement on the band's Facebook page, "The Skull is here to do one thing... rock you with the sounds and spirit of Trouble — past, present, future. The Skull is planning a thirty-year celebration tour of Trouble's debut album, Psalm 9 in 2014.
