Improve our copy to clarify that EMF is (in addition to other things) a music festival

[SamLR]

as noted on IRC we don't really make it clear that EMF is a music festival and there is loud music until late (at least in certain parts of the camp).

tbf I do think this is a comms/website copy issue, the homepage definitely gives that impression imo. The only time music of any form is mentioned on the home page is “chiptunes”. The about page mentions music but doesn’t really set the expectations. Nullsector is basically a “you had to have been before to know it exists” thing.
“The festivities on Sunday night” is the closest any copy gets to saying there’s a party atmosphere that continues after dark
