Stage and events
Dates and tickets first, atmosphere immediately after.
An artist site, a company, a conference: the visitor arrived from a link somebody sent them and they are checking one thing, which is whether they can still go. Bury the dates under a mission statement and they leave, having decided nothing. Lead with the dates and you have earned the two minutes it takes to look at everything else.
The sites here do it in that order, and are still the more striking for it. Open one and see how fast you reach a date and a ticket link.
Nothing here is a mockup. Each one is running on the same machine that would run yours, and putting your own name into one costs nothing and takes under a minute.
