that began on May 5 with their ninth sold-out First Avenue show. They played an "encore performance" of the tour's final sold-out show at The Rock in Maplewood, Minnesota on September 14, 2007. This would be their last live show together. Hiatus (2007-2011) Updates from the band between 2007-2009 were sporadic at best, though Chad Hanks regularly kept fans updated through his personal blog. In August 2008, he commented that drugs had once again become an obstacle for the band, with Hanks himself claiming to have become sober again in winter 2007, while Cameron Heacock waited until April 2008 to attend a treatment facility in California. In September 2008, the members of American Head Charge reconvened in a Los Angeles recording studio to resume work on their fourth studio album. While most of the band spent a week in the studio together, vocalist Cameron Heacock only spent 3 days with the band. Chad Hanks reported that the band had recorded one full song and started working on two further demos. With his newfound sobriety, Heacock found himself struggling with writer's block and unable to find an adequate balance between creativity and maintaining sobriety. In April 2009, Heacock agreed to spend some time in Minneapolis with Hanks as a means of supporting his creativity and sobriety. However, he never showed up. On August 11, 2009, the band issued a press release, stating the band had disbanded. The press release cited singer Cameron Heacock's "inability to continue on a musical career path." "This is not the kind of news I enjoy being the bearer of, but we've been ready and waiting for input from Cameron for almost two years; we've written and recorded two albums worth of material in that time." said co-founder and bassist Chad Hanks. "At this point, he no longer gives being in this band any sort of top priority, which is so sad seeing as how he has such an amazing and unique voice; I couldn't wait to hear it on these songs. "However, we're looking forward to some new blood; a young, hungry soul that doesn't sound like anyone else and is ready to work his ass off. We're more than eager to get back to the mines. This is what we do." American Head Charge received over 300 submissions from hopeful vocalists after the departure of Heacock, which were described as mostly "horrible" by bassist Hanks.
