Are there any fans of Can becuase I want to know where to start and also where to start with Holger Czukay's solo material.

With Can, start either with Tago Mago or Ege Bamyasi. Both are must-haves...and either one should make you want the other.

contrary to what seems to be the popular idea, i find ege bamyasi to be way more accessible than tago mago. as mentioned above, they're bot must-haves though. a bunch of can albums have been remastered recently, those included. pick 'em up.
