What are your favorite songs or albums for illustrating a deep soundstage?

Carly Pearce - Every Little Thing

The drums being so far back create a nice background to the voice and instruments that are upfront.

Wow.
Not only are you loaded with the good stuff, but also sporting the uniformity of the silver/wood/black visual aesthetics, all the way down to the actual turntable…damn!! Way to go!!

The good stuff awaits…

Harry James on Sheffield.  Direct to disk and then remastered on CD.  Recordings have the real ambience, not some artificial mix on a console. 

The Dø
Live at l’Olympia, Paris
Opposite Ways

about 2/3 through is crazy bass atmosperics

Mahler's Symphony No.5 - I just listened to this record all the way through yesterday (DG, Kubelik conducting) and it's a very holographic recording, plus the fact that the music itself is amazing doesn't hurt.
