I first read MegaDrive. I thought it was about the video game system (Sega Genesis, for you Americans), but then after re-reading the title, decided to not even click on the thread.
Now that I did, and after having watched that video in the original post, one question. Dave said he influenced "3 of the big 5 of thrash metal". What's that fifth band he's alluding to? It'd have sounded even more arrogant if he just stated he majorly influenced three bands out of the Big Four.
