One of my favorite recordings of Tchaikovsky's complete 'Nutcracker' ballet--the 1972 EMI with Andre Previn and the LSO--has just appeared on HDtracks. This is another of EMI's recent hi-res remasterings of older catalog material for SACD release (though this particular recording hasn't been released yet on SACD outside of Japan). Looks like EMI did a good job here!
