From a wonderful collabo album entitled "Rome" by DJ Danger Mouse and Italian classical and film composer Daniele Luppi (check out the cool-looking
graphics at his website). They've created an beautiful, aching, honey-textured album whose tracks are lassoed together with Kill Bill/Spaghetti-Western themes.
I think the album is best listened to in its entirety, rather than track-by-track, but these two are pretty stand-out to me.
It's been on the background as I work for a couple of weeks now!
Jack white adds his vocals to the track above; Norah Jones to the one below.
