Awesome thread.
Wolves in the Throne Room is definitely one of my favorite black metal bands. I get a lot of flak from all the other "kvlt" kids when I say that, hipster black metal blahblahblah, but it's just way too fucking awesome. I saw them in Athens once with Krallice...definitely an awesome show. They lit the area with candles, very atmospheric and even the venue they chose was very "them".
I saw Converge + Mastodon on their recent tour with Dethklok. High on Fire was okay...I never really got into them. Converge was fucking awesome, as always. Definitely check out Jane Doe or Axe to Fall if you guys haven't heard, though they are hardcore and not metal. Mastodon is bullshit now with Crack the Skye, but they did play some Remission + Leviathan, which is always awesome. Also, the Dethklok crowd is definitely one of the worst ever. I swear I saw about 20 twelve year olds and everyone else was a stringy haired neckbeard.
You guys should all head down to Atlanta for Scion Rock Fest. Awesome music festival that they just started, and the best part is it's free. Last year they had Neurosis, Boris, Wolves in the Throne Room, Converge, Mastodon, Baroness and a fucking shitload more. Good stuff, we could all have an SF meet up beforehand or some shit haha.
