After Stone Temple Pilots had begun playing together, the band decided to record again, but a lawsuit filed by Atlantic Records on June 12, 2008, made the sixth album an uncertainty.  Atlantic eventually withdrew the lawsuit, and the band's attorney called the legal situation a "misunderstanding".  This is the last album to feature vocalist Scott Weiland before he was fired from the band in 2013 and died in 2015.
