REQ: The Rock House Method Rob Arnold, Chimaira: Song Writing, Riffing and Soloing
Shot in the dark, there are other videos from this series posted here and this one has been out for a long time so maybe somebody has it. It's only available as a download from The Rock House Method these days but it was previously released as a DVD as well and is still available that way from some places. I'd be appreciative of either format!
