Robb Flynn has been playing some solo shows of late, but Machine Head fans should not worry about the band's future. In fact, the rocker revealed in his latest online posting that he and his bandmates recently got in their first jam session hoping to spark material for their next album.

The vocalist explained, "Dave [McClain], Phil [Demmel] 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 and 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."

As for his solo shows, Flynn also provided a recap of what his week of acoustic dates entailed. The vocalist recalled, "The shows were awesome, really, really, REALLY awesome! I needed this so bad. To everyone who came out to these shows and made them such a special and intense event, thank you. They got heavy, really heavy and I had no idea how heavy these would get. Therapeutic. I didn't know what to expect or what they would be like. I made no set list except the opening and closing song. Chose songs we probably won't play live again or at least haven't played live in a reeeeeeeally long time, and cover songs we would never cover. To my surprise I ended up telling a lot of stories before each song. Every time I thought I'd been going on too long with a story, ('am I talking too much?') people would ask for more. In Fullerton I got a 'sto-ry, sto-ry, sto-ry' chant, it was hilarious. It was surprising how fun these shows were."

Flynn calls the performances "a massive communal release" and admits he got choked up by the response on more than one occasion. The vocalist also stated that he underwent a master cleanse and went beyond the ten-day process to make sure he remained sober while doing the performances.
