The Necromancer is one of my favourite tracks. It's just, everything. Shush.
I learned to play the long players like Fountain of Lamneth, 2112 and Xanadu when I first got a bass. Once I got to Hemispheres part 2 I realised my limitations
I guess there's not much variation in Live stuff from back then - CoT was written on the road while touring Fly by Night, and 2112 was very soon afterwards.
It's nice to listen to Geddy's voice from this era too - while the recent live albums are amazing playing, he's obviously struggling to reach those 70s notes with his voice.
