"1970"/"Fun House"/"LA Blues" is just the gnarliest 1-2-3 punch of descending into anarchy.

The A-side is downright samey by comparison.

Are you mad? The A-side has Loose too

Still samey by comparison no matter how awesome it is.

what does comparison have to do with it

if the B side didn't exist would the A side somehow become different music

I didn't bring up the comparison.

that's literally the only thing you brought up

Literally someone else bringing it up.

I see...

I wasn't besmirching the A-side, but the B-side is clearly conceptual. You have "1970", which starts as a more traditional Stooges song but then unravels into something more anarchic once the sax comes in, then "Fun House" further devolves into just a bassline with the guitar and sax interweaving around it, and then "LA Blues" completely deconstructs into balls out free jazzy chaos. Like the band was descending ever further into more radical territory with each song. The A-side doesn't do that and is more traditional throughout.
