I think it was during the 25th anniversary of Sgt Pepper that I read for the first time a critic who dared to say that “this chit doesn’t hold up!” He was right of course. Concept albums don’t hold up, rock operas don’t hold up, the first Little Richard album on Specialty does hold up.

Most musician/groups's first album is the best as they had multiple years to generate good stuff before they became "overnight" successes.
