I remember three bands playing that night. Two of those bands were local, one being Lester Freamon, the other I have no idea, and the third, Deafheaven. Lester Freamon played a cool set, some chaotic experimental punk and hardcore . But when Deafheaven played their set, it was like a doom metal symphony of just loud guitars and drums. And their set was really loud. The singer screamed at the top of his lungs along side some mid-tempo metal riffs. And some parts of their music can be soft and clean, but only for a moment. Then the chaos would ensue. And their music is very epic - I wouldn't be surprised if their 30 minute set at Within These Walls consisted of only four songs.
But I think what makes Within These Walls something to attend to this year would be for the headliners. I can't vouch for their live shows, I've never seen them play before, but man those guys are dope. H20's, Thicker Than Water, is a pretty tight album, and the only one I have of theirs. And Stretch Arm Strong's Rituals of Life is just as awesome, but I first heard them on the Songs from Penalty Box Vol.2 compilation. I heard, Second Chances, and then I was hooked. Like I said, it's going to be a sick show.
