Slow Fuse - Performance is a video guitar lesson presented by David Hamburger and is sourced from Essentials: Fingerstyle Blues.
This kind of call and response between single-note licks and a more double-stop-based vamp is something I've been exploring a lot in my own playing lately. In particular, I've been inspired to do so by the playing of jazz guitarist Ed Bickert. Which may seem like an odd place to get ideas for fingerstyle blues, but if you check out the way Bickert drops in his own chord commentary during his single-note soloing on records like I Wished On The Moon and Out of the Past, you'll see what I mean.
