Having known a couple of opera divas in our time, be assured that the (former) lyric soprano, Amanda Reckonwith, who triumphed in her return to the stage at Pangea, after a 25-year absence, is no slouch. Reckonwith is just as fun, vivacious and full of high drama as she ever was, plus in superb voice (even if she is now a mezzo)"as if her hiatus were 25 minutes instead of years.
