How can you possibly see a lineage from Tony (passionate, innovative, expressive) to Vinnie (creative, bombastic, slick) to the stiff, unmusical Drum-inator. I don't see that at ALL. And as an aside, why can't Lang play with the click on the DVD when he's doing the pad stuff? Couldn't they have reshot it so it sat with the click? Those takes should have stayed on the editing room floor.
