Hey, I don't know if this has been posted here before, and as I don't know what you would call this, I figured I might as well post this. I've been going through the NAMM videos, and a few times, I've seen bassists do a slapped/popped mute "roll." The tone is sort of weird, and despite how I try to emulate how I think it would sound doesn't work, and the way they move their left hand confuses me. What I'm talking about can be seen here: http://www.thelowend.net/gallery/images/namm/shanon1.wmv At about 0:30 - 0:31. (Warning: 11.5 MB download) Is it just a muted pop, double slap, left-hand slap, double-stop mute, and I'm simply overanalying? I apologize if this has been done before, is on this page, or is something really simple that I should be able to figure out by myself. Thanks.
