Anything by Chantal Chamberland, preferably heard on SACD.
I'm a bit surprised at the number of early digital recordings that have featured in the posts so far - Brothers in Arms, Body and Soul, and the Nightfly, all of which IMHO, show up the fairly severe limitations of the digital recording technology of the time. Admittedly, Body and Soul is superbly engineered, but would have been so much better if it had been recorded to 30 ips analogue.
