Xiu Xiu covers the Pixies
Xiu Xiu - Gigantic (pixies cover)
This track is taken from the eighties project, which I can find little about but I do love this track.
Speaking of Pixies covers...
Teenage Fanclub - Here comes your man
edit: Okay after looking for some more information about this song I found one web page that mentions this song and said this is only Jaime Stewart from Xiu Xiu but then again I saw this on another web page with Xiu Xiu being credited. Its all the same to me.
