I like the other posters more, but the first poster probably still conveys the idea of the event better: people having fun, drinking beer, with a live band. You don't get that from most of the other posters unless you first mentally transform those icons into real things, which takes effort.

I'm starting to think that icons are in fact the low-effort way to convey information. It's design you can just throw in anywhere without adapting it to context (except for maybe changing color).
