This is Jojo's first DVD on Hudson music, focusing on hand technique.
The material and exercises within will take a long time to master, so this is maybe not for everyone. However, I think it's worth owning this DVD for the performance value alone, Jojo IS the master! Fun to watch.
Production value is high and the sound is satisfactory.
I highly recommend this and the follow-up (Secret Weapons part 2 - A Guide To Foot Technique).
