Yeah, I definitely see what makes people adhere to his music so much. I only became aware of Allan through a Shawn Lane interview where he mentions him as one of his biggest inspirations.
As far as listening goes, Allan's music is a bit too left field for me but I still went on an escapade of watching live footage from him a while ago and was basically blown away that someone like him existed in that era. I'm a sucker for simpler chord progressions sadly for now.
Question, have you ever listened to The Aristocrats?
What a trio. Not just in the light of guitar but the band as a unit is honestly one of a kind. Awesome stuff.
