The Who Sell Out has been an absolute favourite of mine since I bought my first copy as a budget cutout (like for 99 cents or something) on US Decca in 1971. In fact, it vies for my No. #1 Who fave LP along with Who's Next. I still have multiple copies of the LP. Just as an aside, my favourite press is the US Decca stereo from among the US Decca and UK Track monos and the US and UK Track stereos. Haven't heard all the various other presses...I have the German Phases box back home in storage and some of those in that set are well regarded...I just can't remember how they sound. The opening days of the week bit and the segue into Armenia City in the Sky is a fantastic slice of popsike. The instrumental backing track is hypnotic...love it along with the rest of the album. IMO The Who Sell Out was overlooked for decades for much the same reason The Rolling Stones Their Satanic Majesties Request was given short shrift for so long -- these psych outliers didn't fit the critics' narratives. It's different now, of course, especially with The Who Sell Out as it's now much better regarded than in times past.
