"La Nativité du Seigneur" is a collection of organ pieces by Messiaen, played complete this evening at Saint James Cathedral by high school senior Matthew Johnson. He may be young but it didn't show. He's been a piano student since he was little and later an official organ scholar at the cathedral. It's rare to hear this music played live and complete, and though I've heard more than one recording of it the live experience was so much more intense — so much so that my friend had us go for a drink afterward to come down from it.
