I watched this video of Anne Akiko Meyers playing Morten Lauridsen's "O Magnum Mysterium" for the first time over the weekend. I couldn't get it out of my head, and I keep returning to it day after day.
It has caused me to look up the text and origin of the O Magnum Mysterium and explore more of Lauridsen's and Meyers' work.
As far as I can tell, it hasn't been released as a recording yet, but you'd better believe I'll be first in line to buy it when it is! I had to settle for buying the original choral version for the time being (which is also sublime).
