Suede? And someone upthread was talking about another band dining out for life on two now dated sounding albums? Ultimately, Albarn has produced the more interesting stuff, but he needs to work with good collaborators, which is why his solo albums are so dull and why Blur became less interesting when Graeme started concentrating more on his solo work.
Definitely Maybe is still a thrilling album, Morning Glory could have been even better if Oasis had subbed in their better B-sides, but arguing the toss on this is like replaying a civil war. Damon and Noel came from different places (geographically and thematically) and were both a big part of a hugely exciting time in music and the wider culture. That can be enough.
