The winding walk down to the Los Angeles Memorial Sports Arena, which housed many acts at FYF, is a strange experience. You move into the subterranean layer as the bright L.A. sunlight disappears. It grows dark, and then you move into the dimly lit arena, which is massive and abyssal. The setting gave Slint an actual sense of intimacy. Here was a space that people wouldn’t stumble into accidentally, a place fans had to seek out and find. It gave songs like “Don, Aman” the silence necessary for its intensity to build, while the volcanic closer of “Good Morning Captain” used the enclosed space to build like a pressure cooker. In the final minute over the howled screams of “I MISS YOU,” the crowd finally burst into a fierce mosh pit that was over nearly as soon as it began. For the rest of the weekend the arena housed electronic acts and was a warm and welcome club space, but Saturday afternoon, Slint made it terrifying.
