It is a very good idea to ask to the customers their opinion ; For me , this DVD is absolutely magnificent, every drummer ( and others musicians too ) should have and see this performance, everthing is there : drumming education, jazz and afro-cuban drumming, rudiments, practicing, left-foot clavé, independence, soloing ideas, odd-meter clavé, good and interesting explications about music and "life" ( having the right attitude ), music-business ... Antonio Sanchez is a very, very good drummer but also musician so he can explain his "feeling" and can also share his tremendous musicality. In a intimate master-class setting, he performs both on his smaller traditional-jazz set and his larger kit that he uses with Pat Metheny, playing selections from Pat Metheny Group, along with compositions by Chick Corea. The only "defect" in this DVD is the eBook with transcriptions of exercises, it is too small, not complete, it should have more patterns. Aside this, it is perfect, essential for all of us, Emilio ( France ).
