educatedfilm, I know when the baggy movement was and it was killed off in the late 80's/early 90's around when the La's released their debut. Britpop was a natural progression from Baggy and Oasis brought it to the mainstream with the classic Definitely Maybe. And I forgot to mention the Masterplan wasnt a proper album, it was a collection of B-Sides from the singles off the previous albums(The Masterplan being one).

And Oasis are more than just "manchester rock" obviously seein as they still manage to sell out stadiums on a regular basis and there albums are still selling like hot cross buns in the morning.
