Take Carcass and In Flames and feed them booze and copious amounts of abused substances. Crank up some old Accused and P.I. and let them fight it out in a steel cage match. Take what remains, expose it to radiation and your moms nagging and you will find Gallows End. Metal with European style and a good old Canadian "it's in yo face kiddies" attitude! See them live! They're the band you look like a fool not moshing to!
For physical events that happen at a specific time. For example a concert, or dance performance. If there are multiple shows, you can still duplicate your event to cover them all.
