They were at Suzuki's Melodica booth. I had watched some of their YouTube videos before. Many people would comment that they're not actually playing in real time. Oh they DO!!!! They're actually very good and efficient. They played multiple arrangements of their own YouTube content. It's nice to hear good musicians in person.
