I've been a Sonic Youth fan since 2003. I've heard all of their full lengths, plus all of their SYRs and some other EPs. To me, this seems like the best album for anyone to start with. This also has become my third-favorite Sonic Youth album, behind Confusion is Sex at #2 and Murray Street at #1.
This album is dense with the sort of fuzzy, distorted, guitar noise that Sonic Youth was known for during the middle of their careers. On Daydream Nation, bad recording quality left them sounding underwhelming. On Dirty and Experimental Jet Set, they just weren't quite as generous with the noise. Also, the songs here are as well formed as on any other album they've ever recorded, although I could've done without the pointless, boneheaded Chuck D segment on "Kool Thing".
Besides Chuck D, I can't really find any weak spots on here. They successfully stretched an album to 50 minutes without making it boring.
By the way, that cover art with the high-contrast black & white drawing is killer. On the liner notes, however, is the most dated fold-out mini-poster ever. It's all primary colors, and the band posing for liner-note photographs in gaudy clothes. When my future children ask me what the early 90s were like, I'll show them this.
