Ah. The Koch was, I'm reminded, reissued on CD. And also, a Discogs entry for the original LP, has 31:15 (not 32:07) divided into 13:25 / 10:04 / 7:40 for the three movements/sections of the concerto. cpo is longest in the first movement, followed by the new Naxos, followed by Maile/Lopez-Cobos speediest (if complete) on Koch; in the second movement cpo is again longest, followed by Maile on Koch, followed by the upcoming recording; in the finale, the new recording seems to be slowest at 8:55, followed by cpo at 8:48, followed by a speedy (assuming not cut?) Maile at 7:40.
