Live Forever in the same time period

I was watching the documentary Live Forever this evening, which was quite interesting though seemed to miss out an awful lot of anything that didn't happen to Blur, Oasis or Pulp. But, rather than get into discussions of what could have bene included (though I'll just mention in passing Screamdelica and Richey Edwards' disappearance) it prompted a sort of explanation as to why Blur and Pulp were able to move on musically from the mid-90s while Oasis seem stuck in the same groove.

Essentially, it comes down to the fact that Blur and Pulp both recognised that the period was coming to an end, that the party was over, and made albums that were could be seen as 'comedown' or 'morning after' collections. Pulp's This is Hardcore is probably the best example of a look at the dark side and after effects of hedonism. However, Oasis never realised it was over, or if they did, they never admitted it to themselves and just continued on the same track, with no real thought given to moving or changing with the times and slowly heading down the road towards self-parody. Oasis are like the people at the end of the party still trying to encourage everyone to have one more drink, one more dance when everyone else is heading out the door and the host just wants to kick everyone out, turn the lights out, go to bed and deal with the mess in the morning. It's not the prettiest of sights, really.
