As we've discussed previously, the German heavy metal band (get it? GET IT?!) Compressorhead consists of four robots who perform blistering rock songs, including this recent live cover of AC/DC's hit "TNT." After all the advancements in robotics over the years, it's nice to see we're actually getting somewhere worthwhile. Now, when the robot apocalypse comes, at least we know it'll have an awesome soundtrack.
