Query: Obscure techniques

Problem is that the techniques are crazy advanced. Definitely not a beginners, not even an intermediate dvd. Maybe not even advanced; probably few drummers will ever master these techniques.So it comes across more like a talent show.That said, these are cool techniques and I will practice them. But they will not be the bread and butter of my routine. For thatI defer to the much simpler (yet powerful) approach of the Tommy Igoe lifetime hands video.Time will tell whether these 'super techniques' provide any value to my playing... they may. But I am not going to let myself be intimidatedby their complexity in the meantime....*** edit **Okay, gave it another star (on second viewing). The development of the moeller technique is first rate....
