If what you are after is playing that riff up to speed, I have some suggestions.
The main riff he is talking about doesn't appear to be too crazy, and as he mentioned it's a fairly traditional blues pattern sped up. Watch the video, and try and catch onto what he is playing at the beginning and work with a metronome to keep it up to speed (
around 160.)
I know this sounds basic, but there are times when that basic routine is the best way to go. Start slow, and work your way up. By what I have heard of your playing, you are in the groove of the blues feel but with this it's a matter of you getting it up to speed. Treat the same way as any other fast lick you are trying to learn.
Hopefully this helps? :confused:
