FARK! It's too early. I read that headline and thought Bobby had finally lost his marbles. I had to click on it just to find out what he was talking about before ringing the men with the white coats for him. Then I realised it says he's not surprised by thrash metals relevance and not thrash meals relevance.
I know everything in thrash meal, and metal, gets compared to Metallica (their meals would probably be better than Overkill's) and its a bit unfair because like them or not they are a one off breakaway of the scene, kind of like when you work out an average score you often remove the highest and the lowest number to remove any obvious bias. But there is a massive difference between a band like Metallica and Overkill that does set them apart and it sets their music a part. Overkill posted some pics of their gig in Memphis on FB and you can clearly see the crowd is low, the comments confirm it and you could nearly do a head count via the shot (not quite), but they embraced it. The venue is smaller, the crowd more intimate and the sound would really thump a place like that. I've sure given the circumstances Overkill could play an arena, but there is no way Metallica could play to a crowd as small as Overkill did.
Bobby talks about thrash meals relevance, it's because of how accessible bands like Overkill make it. Maybe it's not relevant to everyone, but no fan wants it to be like pop music where gigs are only played in arenas and world tours take 5 years.
