Anton Bruckner. Came close but not close enough. Still one of my favorites.

I'm amazed at how many people have never heard of Richard Thompson, Geetar Gawd! Old or new, his work is beautiful.

Another favorite is Sam Phillips, the singer, not the producer, though she is married to a producer - T Bone Burnett. Fan Dance is excellent and Classic Records has two of her older works available on 24/96.

Mark Knopfler - Flying to Philadelphia
Catie Curtis - My Shirt looks Good on You
Pearls Before Swine (Tom Rapp) - anything
The BoDeans
Precious Bryant - blues
Otis Taylor - blues
Dread Zeppelin - Un-Led-Ed (a real hoot!)

I must have been waiting for this thread! These are songs/pieces that can move me. Here's my list:

FOLK
Most of Stan Rogers (folk category):
Album - 'Fogarty's Cove' / Songs - "Fisherman's Wharf", "The Wreck of the Athens Queen"
Album - 'Between the Breaks (Live)' / Songs - "Barrett's Privateers", "Witch of the Westmorland" & "The Mary Ellen Carter"

Judy Collins: Songs "Sunny Goodge Street" & "I Think It's Going To Rain Today"

Pentangle: Song "The Trees They Do Grow High"

Leo Kottke: particularly the albums "6 & 12-String Guitar" & "One Guitar, No Vocals"

J.J. Cale:
Album - 'Special Edition' (best songs) / All especially songs "Crazy Mama", "Lies" & "Don't Cry Sister"

Robbie Robertson: 1st Album S/T

CSN &Y on '4-Way Street' - "Cowgirl in the Sand"

Quicksilver Messenger Service: Albums - either 'Happy Trails" or 'Sons of Mercury' (Greatest Hits)

It's A Beautiful Day: Song "White Bird"

CLASSICAL
Jussi Bjoerling & Robert Merrill - "Au Fond du Temple Saint" (duet from Bizet's 'The Pearl Fisher')

Bach - Concerto for Two Violins (Heifetz) RCA

Jean-Pierre Rampal/Lily Laskine - Japanese Melodies (maybe the most relaxing music I've heard)
