What was important to me was making sure that my lip buzzing formation was not too different from the way I play. I call it a Peel Away Exercise. I'll leave this file up for a few days. It is downloadable. I'll need to take it down in a few days as Mp3unsigned.com may not like this file. Here's the link:
