You may be familiar with mashups, but this has to take the cake. It’s a mashup from three music instruction videos.
And just so I don’t seem like a bandwidth hog, the original page in context is here. (Even though I’m being less of a bandwidth hog by linking straight to the video because I’m not forcing you to download three long QuickTime movies simultaneously! But don’t get me wrong; all three are worth watching… as long as you have broadband.)
Very cool idea. Gets a little stale (and not as well-executed) by the end, but still impressive. And of course, Beaver Felton is the guy who sold me my Music Man StingRay 5. (True, I bought it from his shop, not him personally, but I did have direct contact with him personally both by email and on the phone. Not that that makes me cool or anything.)
