This guy Corey Hunter has posted a bunch of cool video lessons on YouTube. A lot of the lessons may seem fairly basic but there are a ton of good rhythm ideas and chord voices in there.

Couple of samples:
fuckin A. I was actually watching a bunch of his videos sun AM. I was checking out the black metal creepy chords mostly. I like the droning demos because my style is heavily droned too, so those really make sense. I learned that the whole trick is to find a cool chord form that will sit in your drone, and the 3 notes you can move one finger around to up the creepy.
Then I realized that I have 5 yr old recordings of doing that idea. so that was awesome getting a whole new dose of things to try which actually are adding to what I already use.
if people don't realize the Godzilla sized resource pool for learning anything, that exists on youtube, you need to check it out.
I was watching this, maybe brit dude, who played 50 metal/famous guitar player style riffs, but then he broke each one down, flashed some tab for each one, and showed the main tricks/techniques he saw in these guys. I have never picked up on so much in one video, wow.
edit btw, I didn't watch the stoner vid you linked, BUT I did trance out on that tshirt in the black metal technique videos he did also wearing it. at fisrt I was thinking "uh oh" when I saw the text in the early vid. then later I saw the art. WHEW! ok, lets learn some black metal...
I like Corey's stuff. He's definitely helped me understand some things doom and drone related.
Jibberish, you got a link for the 50 riffs dude?
yes. in fact I was impressed enough to start its own thread for it. I never learned so much shit from one video ever.
his teaching method, of all those 50 jams, is awesome.
