Jambinai, a South Korean prog-rock ambient instrumental band playing traditional Korean instruments mixed with guitars is the kind of band you stumble across at SXSW. It’s these weird surprises that make SXSW so special. Tonight, Jambinai were bringing their unusual sound to London. So I thought I’d catch up with them to see if they were as good as I remember. Luckily, they were everything I remembered.
