Masked nu-metallers Mushroomhead shook things up in 2015, parting ways with co-founding keyboardist Tom Schmitz and 11-year vocalist Waylon Reavis (leaving the squad with a mere two vocalists, one of whom rejoined the band in 2013 after nine years away). Now they're moving ahead, hitting the studio this fall to record their ninth album, the follow-up to May 2014's The Righteous & The Butterfly. After back-to-back four-year waits, it looks like the group will be back a little quicker this time.
