The Coven hosts a few performances here and there but the one that stood out the most recently... well, they used a streaming service to stream their music in real-time so it synced up exactly with their emotes, lyrics, and dancing. They incorporated spell effects, dance emotes, even non-dance emotes, and I'm pretty sure they have everything macroed with timings so it syncs properly with the music stream. Play the music, hit the macro, sit back and watch as people go nuts. It's magic.
That is, frankly, an almost insane degree of effort in the setup, though.
