Te Deum (St. Ambrose)

From the YouTube notes:
Monks of the one of the Abbeys of the Solesmes Congregation sing this beautiful chant. The Te Deum is attributed to two Fathers and Doctors of the Church, St. Ambrose and St. Augustine and is one the most majestic chants in the Liturgy of the Church. It is sung in traditional seminaries and monastic houses at the Divine Office and for Double feasts of the First Class, The Nativity, Easter, Corpus Christi, Epiphany, Pentecost and those which have an Octave. The solemn Te Deum is sung on all occasions of public Church rejoicing (in Traditional Catholic Churches)
