No one seems to be looking at classical, but the Telarc release of the Atlanta Symphony Orchestra's "The Firebird Suite / Prince Igor" was one of the most innovative recordings of its era - one of the first (if not THE first) digital recordings of any type of music. We used it to show off JBL, ADC, Klipsch, Macintosh, B&O, Marantz, Technics, Empire, Onkyo, and other top shelf equipment back in the day. The finale of Firebird on side one gave everyone goose bumps. Shaw exhibited sheer genius and the ASO was at its peak.
Best if you can find a copy on Vinyl.
