This or That?

^ haha, could not have summed it up better! I, frankly, still cannot digest Warrior after countless tries. "Where Have I..." all the way! 

Hate to say it, but you mentioned a band I do not have any use for: MGP. Does it have Canterbury aspects: sure! Is it Canterbury: NO! I hate drawing boundaries on music, but anything proclaiming to be capital C without that "British whimsy" flavor is not it. This band is the perfect example. Supersister did a much better job! 

Having said that, Genius Hans, inconsequentially. 

^Anybody?

No worries i agree about lumping bands like MGP and Supersister under the 'Canterbury' heading.. i was aware of both bands before i came on PA and as far as i was aware these bands prime influence was Frank Zappa and the Mothers of invention after their early tours of Europe and Scandinavia, possibly along with Soft Machine.. Does it bother me? no. Actually i prefer Supersister to MGP but do just like that Early European avant-Jazz-Progressive sound generally

^ perhaps, I shouldn't get so emotional about such things, it's all music after all. I do sense a much stronger Zappa influence from these bands than anything "Canterbury" per se. YMMV

sorry *Cristi

^ Really, the OP said that the picks must be from the same artist, but I will pass the caveat that different artists can work IF they apply to the rest of the criteria. The two listed are from different periods, but share style and the so-called symphonic-prog revival cred

Anybody take on the challenge of Cow or, worst yet, listen to both albums? 

or

^ anybody with more knowledge than me wish to take on Thieves Kitchen's picks?
