A funny thing happened to me on the way to the Morbid Angel show. I had popped into the Union Square Best Buy to pick up a copy of the new “Man Of Steel” film on Blu-ray and as my friend and I walked past the park on our way to a fave watering hole Duke’s, we heard applause, riffs and more applause. From the distance I could see a stage lit up and I figured it was some sort of contest or demonstration. It was not, and when I got to my destination I learned it was Compressorhead, the band that is composed of robots and they were doing some kind of presentation in the park. Check it out.
