I haven't listened to much Sonic Youth beyond Daydream Nation (just NYC Ghosts & Flowers and a scattered assortment of singles etc), but Daydream Nation is, of course, wonderful and the rest of their stuff tends to be good value, so I picked up Experimental Jet Set as much on the strength of that track record as because of the record's killer single, "Bull in the Heather".
The album turned out to be pretty good, too. Less sprawling and epic than Daydream Nation, and perhaps a half-step closer to the mainstream (all things being relative), Experimental Jet Set generally doesn't rock as hard as that earlier masterpiece, and its quieter moments tend to be more pop-oriented than atmospheric-ambient, but it retains that characteristic grinding, fuzzy-yet-spacious Sonic Youth feel, and there's still plenty of interesting stuff going on. A really good record.
