For anyone unfamiliar with Xiu Xiu, "Apistat Commander" would be the song I'd recommend starting with when checking out this band. It's easily the most accessible thing they've recorded to date, but with that said, there's really not a whole lot about Xiu Xiu's music that screams "accessible," so approach with caution.
The song starts out innocently enough, with singer Jamie Stewart's barely audible moan and minimal synth backing, before ripping into a "cathartic attack mode" that sounds something like Nine Inch Nails raping the Cure. The song's best moment comes when Stewart screams, "oh, this relief/it's the oddest thing/ohmygod/ohmygod/ohmygod."
Robbie is more noted for bringing a wicked sense of humour to his tunes but this one certainly is an exception. He may have origionally conceived of it as humourous but I think it was producer Steve Albini who convinced him to play it totally straight. What they got was one of the most harrowing listening experiences ever.

One of the finest moments of she-glam ever, Siobhan Fahey's long-buried-but-about-to-be-unearthed-for-reconsideration third Shakespear's Sister record has many harrowing moments of brilliance, but none moreso than "Do I Scare You". Opening with a swirl of Eastern-cum-goth keyboards, boasting "there goes the year/in doctors bills and sleeping pills", Fahey's voice squeaks, snipes, and snarls throughout, ultimately climaxing on the verge of pumping lyrical lead into a deserving partner (and listener) by the final bridge. I can't think of a celebrity meltdown on disc that was ever this catchy.
