After a bit of a break, Mike Nelson’s ready to fire up those cylinders again, or some such car metaphor. His next track will be just that, his and his alone. He’ll be waxing sarcastic on the first two episodes of NBC’s Heroes. If you’re not familiar with Heroes - well, then, you’d be a sane human being. But if you like invincible cheerleaders sticking their hands down garbage disposals and having their chests cut open, then you’re sure to enjoy it. That Hayden Panettiere, such a cutie, even when disemboweled. The horrific, gender-bending poster is behind the cut, where it belongs. The commentary hits the interpipes on September 4th.
