Alan originally mentioned these in his "cpo 2015/6 catalogue" post back in June of '15, but they are now within a few days of being released - initially only available at jpc of course (as nearly as I can tell). This apparently concludes the Molique string quartet "cycle", let's hope the good folks at cpo are in the mood to complete some other cycles as well. ::)
