I read in some interview with Galder from Old Man's Child, that he enjoyed watching TV

I got the impression after watching the making of the wretched spawn dvd that Pat O'Brien is into guns.

Well Frank Mullen from Suffocation certainly is into guns from what I hear.

I read Mike Scalzi from The Lord Weird Slough Feg teaches Philosophy in Religion. His students say he tends to rant a bit, and he wears black everyday. He says music is still his main priority, so I guess that counts for this thread.

It's that time again:

Indubitably, but the fact that he's wearing a Nocturnus shirt makes it all the more awesome, if not for the contrast.

I really hope you're trolling.

He's also a vegetarian. Chatted with him and he said it was especially hard being one while on the road.

Bobby Blitz's wife owns a chocolate shop... Blitz is likely also involved in it.
