The politics of rock & roll is that a lot of people want to be fried out of their skins by the most scalding propulsion they can find, for a night they can pretend is the rest of their lives; and nothing can cancel the reality of that night in the revivifying flames, when for once in your life you were blasted out of yourself and the monotony which defines most life anywhere; when you supped on lightning and nothing else in the realms of the living or dead mattered at all. (Lester Bangs, paraphrased)
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.
