I have to be honest, I wasn't aware American Head Charge were still a going concern. Nor did Cameron Heacock, apparently:
A statement from bassist Chad Hanks reads, "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.
"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."
Yes, the band are going to continue, if they can find someone else to do the singing.
