Machine Head and bassist Adam Duce have parted ways. According to a brief band statement, "the split is amicable, and Machine Head would like to wish Adam the best with his current and future endeavours. The band will continue on for the time being as a three-piece and have begun the writing process for their follow-up to 2011's Unto The Locust. A late 2013 release is projected."
In late January, Machine Head frontman Robb Flynn wrote in his General Journals: Diary Of A Frontman... And Other Ramblings column that "Dave (McClain; drums), Phil (Demmel; guitar) and I practiced the other day, and it was a really productive first jam session, McClain had about five rockin riffs, Demmel brought in the skeleton of what feels like a great song, I had a few riffs that we rocked on, no full songs, but solid riffs. It felt good, good to be moving on from Locust, super proud of that record, but it's time to move on, and we're ready to move on. Bring on the future with an open embrace."
