ProgArchives is the place I have frequented a lot ... the majority of my posts are in the Krautrock threads, as too many of the threads are by little kids trying to find out if there is music out there, and asking really thoughtful questions like ... best female in prog ... best dick in prog ... best keyboard player in prog ... you know ... the kind of things that really made us remember this stuff for so long ... it never was about "best" ... it was about the expression and different countries did things differently, and then some ... my only concern about "progressive" information in this website is that it is a veritable cemetary and there is not enough information on bands and their work, and they are not capable/willing to update their information and add some of the interviews they have, to the album/band information to create a more cohesive location for this information, that would be better than Wikipaedia is becoming. In essence, PA is a deadzone and will likely fall apart because they are not willing/capable of improving to help the genre. They are just a huge behemoth that has gotten so big that it can not even have a manicure, let alone a pedicure.
Saddest wast of information I have ever found!
Some "general" thoughts about "prog":
Italian - usually classical minded and some are very strong in that area, that is within a composition context as in classical music, rather than rock-n-roll
French - Extremely independent and very good at experiments since they are always way out there ... with no rhyme or reason. But this is very good when you hear Ange, who was inspired by Jacques Brel a lot more than ... herrrr ... Genesis ... Mr. Decamps is, by far, the best "actor" singer there is in rock music.
German - Very independent and don't forget that their music schools in the late 60's and early 70's went on an anti-western music thing ... that yielded a lot of stuff that ... was not what Scorpions did later or stood for! But they got famous and told the estudantes and professors to get ____________!!!
Spain - Massive inspiration from Yes more than anyone else, heavily combined with the Spanish guitar work and sound. Some variations are also strange for most liteners and you can find fandango rock, progressive rock and at least 5 other variations in Spain ... and all of them very independent and different ... and equally good.
Japan - Very different, but in the end, their best known was for having helped develop synthesizers with their bands. Yellow Magic Orchestra (Riuichi Sakamoto) is heavily known here and was a heavy hitter in the early days of Roland, and Korg. The music in Japan differs a lot and aside from their heavy amount of commercially pushed out pop (just like anime), which is massive due to its sales in Tokyo, their more progressive music tends to be ... hard to find, but is there. A lot of fusion bands. Hybrids like the early days of Sadistic Mika Band were the odd balls in the midst. Totally independent band with a psychedelic fun first album with satirical songs (Mamma Doesn't Go to Bapu Since Daddy Died!) to the outstanding album "Hot Menu" with its excellent take on Alan's Psychedelic Breakfast. The market for a long time was dominated by many individuals that went on to become massive keyboard artists on their own, including Kitaro (Far East Family Band, Chronicle), Stomu Yama'shta (better known for his work in London), Yu Mai, and so many others. All of them very good in their own individual way.
Latin America - Only Archie Patterson (Eurock) has spent a considerable timewarp listing these folks. And he is 2nd to none in that area. However it is really difficult to make a choice, although these days everyone of these artists has a location on the web for us to check, which gives these folks way better access than before ... when you could not get anything, and no one ... NO ONE ... even thought that these folks could do anything. They can, and they do. In Brazil, the better known stuff has always tended to move towards "jazz" which is more accepted than the street music, that is still considered "pop" and not really "music" for the most part. Egberto Gismonti, stretched this real in jazz to smithreens and he is the Brazilian Keith Jarrett and then some.
