A lot of tricking loses its martial arts quality in the pursuit of bigger, spinnier tricks. Danny, however, makes everything FIERCE. Amazingly fierce. Every kick looks like it could take your head off, even if it comes after 720° of spin - that's not easy.
His arms are always moving efficiently to speed up his movements, which takes an extremely long time to develop. Nobody tells you where to put your arms most of the time in tricking, so you need to figure it out through experimentation. You can really see it in him.
Danny is currently performing with Jon Chu's Legion of Extraordinary Dancers on the Glee Live tour.
