Strings: Beach Boys - God Only Knows
Piano: Tom Waits - I'm Still Here / The Walkmen - Wake Up
Voice: Bjork - Aurora / Skip James - Hardtime Floor Killin' Blues
Drums: on Miles Davis' - Blue In Green

Still working on some other instruments and stuff.
These were just the ones that occurred to me straight away.
As much about the recording as the performance in these cases...
