Hail The Sun & The Fall of Troy at El Rey

Four bands deep into the progressive post-hardcore and math-rock end of things, with Hail The Sun and The Fall of Troy sharing a bill that would have broken Myspace in 2007 and still holds up fine now. El Rey is a standing-room floor situation with a sound system that rewards loud, technical music, which is exactly what everyone on this lineup delivers. Tickets are through Hold My Ticket, so grab them ahead of time since the door situation for shows like this tends to get chaotic.
