Swans (the band, not the football team or the waterfowl) are astonishingly terrifying. I watched them in a warehouse with my brother in a suburb of Melbourne when it was 40 degrees outside and probably more inside, and the sound was a little out of control, and my bones and organs resonated so much I felt like I was having an attack of some sort, so I walked out of the warehouse for a break in the ridiculously hot sun before venturing back in. I've heard that people have been known to vomit from the intense noise of their performances, so maybe I did okay.
But what a sound. What a grinding, angry, defiant sound. Later I bought a shirt that features the baring teeth of the animal on the front of the album The Seer (above). I'm told it scared an old woman the other day. She didn't even go to the show.
