There's something rather lovely about a surprise acoustic set in a public park, isn't there? Justin Bieber rocking up to MacArthur Park with a few mates to play material from his new album feels like the sort of intimate moment that reminds you why live music still matters, even when you're one of the world's biggest pop stars.

It's these spontaneous moments that often become the ones people actually remember.
