A few months back I caught Backtrack, Alpha & Omega and a few other bands in San Francisco. Criminal Instinct from Atlanta, GA is a band that I had never heard of before and they were the openers at the show. Unfortunately, I walked in during their last 2 songs so I didn't get to see their whole set. From the couple songs I did see, I was impressed enough to buy their demo. I am glad I did because it is really good. The vocals are right up my alley, really gruff vocals that remind me of 86 Mentality and Cold Stare. You can download all of their stuff for free from their bandcamp, so there is no reason not to check them out.
