My brother visited for a weekend and went busking in Hongdae. Unfortunately we had torrential rain for most of the weekend, but it cleared up enough for him to go busking for a short time. He has performed in many countries but this was the first time in South Korea. A lot of people commented later saying they wish they had known he would be playing, but until the last minute we really were not sure if he would be able to. He will come back sometime though. My brother is a full time drummer (and also plays real drums of course), he plays in bands but also regularly does bucket drumming. A video of him playing went viral a few years ago and since then he has been invited to play at events around the world. He also does a lot of live streaming now where he teaches some drumming techniques or streams his busking.
