Revocation’s Dave Davidson (whose parents probably are fans of Kris Kristofferson) is at it again with a new Episode of his “Thrash Course”-video-column on the Guitar World Youtube-Channel.

This month he goes over the use of the diminished scale in the pre-chorus and chorus-section of the title-track to the band’s latest album “Deathless”.

Watch it and learn something – if you can stop drooling over his Jackson Custom-Shop 7-string-Warrior.
