Hail The Sun & The Fall of Troy at El Rey

Two bands who never quite fit their scene’s labels share a bill that should appeal to anyone who liked their mid-2000s post-hardcore with actual rhythmic ambition. El Rey is a long room with a solid floor mix, so getting toward the center pays off for a show like this. Tickets are through Ticketmaster, which means fees, so buying sooner rather than closer to the date is the move.
