Some bands have been here for most of your life. Others have been here longer than you have even been alive. Mayday Parade has been a band for twenty years. All Time Low has been a band for twenty two. The crowd reflected that timeline in full. Some people first heard these songs on burned CDs and shared iPods. Others found them on streaming years later. Different ages, different entry points, but everyone already knew the words. This wasn’t nostalgia. This was continuity.
