So i decided i want some refreshment and have now decided to buy some dvd's, never tried that before. I know some basic stuff of both techniques but i wanna improve. So what do you think about the'se dvd's: Slap bass program and the art of tapping or should i get something else? And by the way, i really wanna learn double thumping.. Together they would cost about 100$ + free shipping to sweden.. Another thing is that they are on english, no subtitles? If so i wanna know the way they speak, fast? Or is it most look what he does?
