iTunes shows 30 Aug as the release date for Hyperion's RPC #79 release, Pfitzner E flat major PC & Braunfels' Tag und Nachtstücke. Speculation on an earlier UC thread was that the Hyperion release might include the Braunfels PC, but his Tag und Nachtstücke will be the piece. After just the first round of snooping around the internet, this piece is being ID'd as a "posthumous work, formerly op. 44", and dates from 1933-34.....so Hyperion's "Romantic PC" label notwithstanding (and understanding early Braunfels vs later), probably unlikely to be suitable for this forum.
