Masking the Harmonica

I just wanted to point out the Gary Smith segment with Dave on this subject of masking the harp.
I've been told this idea before when playing with backing tracks, stay on just 2 hole till you sound musical then add a hole etc. I got to say I have a whole new veiw of this skill after watching these 2 guy's demonstrate how it's done.
These lessons 1-7(?) are gold! I will return and listen to these much like the soloing video for a long time and incorporate this into my practice. After years of trying to learn and teach myself things you know when you hit pay dirt.

Thanks, Gary and Dave for the mother load!!!!
