Alexandar Zivojinovich (OK..............Lifeson!!) may be in the top ten all-time underrated rock/blues guitarists, Mike!! Very versatile and inventive..............remember Rush's heyday was in the 70s-80s when they were inventing many of the styles and techniques we take for granted today!! I just got my GuitarTricks notification about my annual renewal...........perhaps I should make it conditional on you doing a nice study into the depths of Alex's great guitar playing that is such an integral part of that great band!!?? Nah...........you did get in that dynamite study of another super rock guitarist generally overlooked......Mr. Pete Townsend..........but getting into some of what structure and scales and techniques that fueled Rush via guitar would be awesome for all!!
