Still waiting for the one-handed roll video to come, but as to the technique JamesC mentioned. I fell on this a year r two ago  totally by accident, when I was playing a kit with a hi-hat waaayyy too low. I ended up hitting my snare stick and it rebounded perfectly.

Then I practised it for a while, working out the balance point the stick should be at when hitting it. It was one of these things that just took practise to realy get it going. Now, I use it in grooves in the same way I discovered it!

I don't know - i just tried it and it works fine for me. Do you have AOL or some other funky browser that might be limiting what you can download? It's a BIG file (10MB), so maybe that's too big for your system?

I had this trick going for ten seconds the other day real good but then it fell apart and I couldn't get it back. I was useing a 12 inch snare where the rim is no higher than the side of the snare head I think you need a taller rim to get it going also probably a 14 incher. 12 inchers have a weird feel to em and they suck, they suck for multi bounce rolls if anything they are good for only single stroke playing and the snare on the bottom has no sensitivity at all. The snare barely produces a sound unless you hit it really hard then it sounds like two 2x4's smaking together.

I think it is easier to learn on a 14 inch snare.  I learned on a 12 inch piccalo snare myself.  Johnny Rabb can do it on anything in his setup, including his cowbell!
