So fucking jealous of that lineup! Especially Asphyx, as it seems like they never come to the US, and havent to the east coast in even longer. One of my favorite bands and I cant even remember one instance of them touring remotely close to where I live in the past 10 years (someone is going to bring up a show I missed I bet). My friend caught D666 like a week or so ago and didnt even let me know!
As for the moshing, dude idk. You may think you enjoy it more while standing there with a beer in hand, but moshing and letting yourself go wild can bring about an enjoyment that standing there and banging your head can't quite deliver. Some moshers are just dumb fucktards as you say, but usually a bit of moshing during a good set maximizes my enjoyment.
As for my recent shows, I saw Conan for the second time at a dive bar in Philly last month. Then last weekend I went to the Philadelphia metal and beer fest with Horrendous, Pallbearer, At the Gates, Sumerlands, Incantation, Repulsion, Mayhem, and Carcass. I never saw AtG or Carcass before, and they were both fucking amazing. Found the guys from Horrendous in the pit during Mayhem, and they said they have a new album coming towards the fall of this year, which I didnt know about and is awesome to hear. I injured my knee in the Carcass pit, but fortunately I dont think it is anything serious. Got tons of free stickers from the beer vendors; the Amber Smashed Face beer that Cannibal Corpse sponsored or whatever tasted great and I grabbed a handful of badass looking stickers.
After the fest we smoked a bowl and went down to the aftershow at the Kung fu necktie and saw Primitive Man play a quick set. The small dive bar was the perfect location for such an intense savage sludge band, great stuff.
