The group also released a mixtape called "Marxmen Cinema" (under the name The Marxmen), as well as a self-titled rap rock album (under the name Mash Out Posse) recorded as a collaboration with heavy metal group Shiner Massive. In 2004, Damon Dash sold his share of Roc-A-Fella to new Def Jam president, Jay-Z, and kept M.O.P. on his new label, Dame Dash Music Group. The group was left feeling uncomfortable with the situation. They announced their departure from Roc-A-Fella and Dame Dash in May 2005.
