Not too many classical fans here so I’ll give it a try:
Claudio Abbado, Berlin Philharmonic, Beethoven symphonies 2 & 5, DD&DTS 5.1.
Nikolaus Harnoncourt, News Years Concert 2003, Vienna Philharmonic, DD&DTS 5.0, a real hoot if you like good time Strauss.
Anne-Sophie Mutter, A Life with Beethoven, 2 channel but it’s only violin and piano, and Anne-Sophie is one fine babe.
Moody Blues, A Night at Red Rocks, 2 channel but a beautiful outdoor setting and the boys are in fine form.
Crosby, Stills & Nash, Daylight Again, DD5.1, electric and ass kick’n.
Simon and Garfunkel, Old Friends, DD5.1, EXCELLENT if you grew up in the 60s you want this it’s ‘far out man’.
