Every major artist that existed in 1967 made some sort of conceptual record (or seemed like they did) and The Who were no different, although in their career arc it feels like warmups for the real heavy material that was to come soon afterward. This one had a very campy cover spoofing advertising and pop art, and some of the content within did that as well. Most of the sneer and leer from the first two Who records was packed into "I Can See For Miles" and amplified for miles and miles, which of course, was undeniably great. The rest of the record got bogged down in the concept, although some of this stuff sounds like 70's Who songs that are just not as polished. It's been re-issued a ton of times, including a 5-disc version with over 100-plus tracks, so yeah, you can say it's a well-liked record. I'm not head-over-heels in love with it – or most of what The Who did, for that matter - but understand its' significance.
