Mute, uh..."roll" ?

[FoxfireBass]

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:

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.

I didn't really see anything special at that time in the video. Just a quick little slap pop lick. Maybe you're talking about the hammer on "doublet" things?
EDIT: Is it just me or is he really just barely touching the strings for slap?

That's more of a guitarist kind of left hand slap -- the usual bass way is to fret a note with your index finger and then slap your middle finger, ring finger, and pinky on the strings (all done with your left hand, of course).

All very useful techniques.

Ah, must be a raked triplet.

Thanks much. Wasn't getting the "right" tone (at least, to me) with a left-handed slap.
