Please forgive the length of this post: I second (or third) the Barber Adagio, Albinoni's as well. Would also add Rachmaninoff 2nd & 3rd Piano Concerti, Keith Jarrett's "Hourglass" from "Staircase/Hourglass/Sundial/Sand" & "My Song" from same release, both on ECM, Lyle Mays' "Close to Home" from his first solo release, Pat Metheny's "Always & Forever" from "Secret Story", Rachmaninoff's Vocalise, 4th movement of Beethoven's Ninth, J.S. Bach's Fugue from the Toccata & Fugue in D min, King Crimson's "Starless" from "Red", Miles' "Blue in Green", Coltrane's "A Love Supreme", Louis Armstrong's "Solitude", Metheney & May's "Sept. 15th" from "As Falls Wichita". Bill Bruford's Earthworks' "It Needn't End in Tears" from their 1st album. King Crimson's "Two Hands" from "Beat". Chopin's Etude 10 in E flat, his "Revolutionary" Etude, and Liszt's Liebestraum. Okay, there's my three.
