This is the RCA Living Stereo (recorded in 1956 and remastered for digital in 1993) of Bartok's Concerto for Orchestra, Music for Strings Percussion and Celesta plus Hungarian Sketches; Fritz Reiner conducts the Chicago Symphony Orchestra (in their prime).   I purchased this album new and CD playing surface has been professionally treated using Optrix and the CD has been de-magnetized.  Also included is a rave music/recording review of the outstanding attributes of this release.  From my private library.
