frisell trio live

Heya, just curious about a few things... I recently got a few tracks by the Frisell trio live off Soulseek - they are named as live in Roccella Jonica. Anyone know when this was, and who's in the trio? Also there's an effect he uses on 'Shenandoah' which he's used a lot on albums but I always assumed it was overdubbing, seems it's not. Sounds like delay + pitch shift i.e. he plays a note, it comes back half a second later but up an octave or two... any ideas on what this pedal is? Thanks, Julian.
