Most people when they think of Delibes think either his operas - Lakme with it's renowned flower duet and bell song being the most famous, and perhaps also his choruses, and well ... ... ... that's it. But in fact that's not it, or not entirely it, he also wrote some religious music including this setting of the Mass. It's beautiful and as a piece of music its quality speaks for itself. In fact I've never understood why recordings of it are so hard to get.
You can hear the influence of Delibes' love of music for the theatre in the dramatic and lively Kyrie and Gloria but it's his Sanctus which is downright angelic, the hushed and serene O Salutaris, and the reverential Agnus Dei which really make this Mass special. It's a lovely piece that lives up to its name - it really is short around fifteen minutes with lovely flowing lines and a gentle lyricism that's fairly easily attainable by most choirs. All of this makes it a fairly popular part of the choral repertoire - there are some very nice performances here on YouTube, but for some strange reason there are very few recordings of the Mass in its entirety available commercially. Enjoy :-).
