I contacted the PSO directly. Contrary to everything that was stated here, symphonies 2 and 6 will be separate issues (and not combined), and they were both recorded in Heinz Hall. Expect M2 sometime late spring (which will mean early summer) and M6 sometime before the end of the year. That makes sense to me, as none of what was stated previously made any sense at all (no offense meant in saying that, as I know all previous postings were sincere).
