Taken from NLM
On the Vatican Radio's Liturgical programmes you can tune in each day to hear Mass in Latin, but also the Divine Office in Latin as well (Lauds, Vespers and Compline).
In addition, an NLM reader tells me, by way of Sandro Magister apparently, that the Mozart 'Coronation' mass is being sung by the Vienna Boys Choir accompanied by the Vienna Philharmonic in St Peter's Basilica tomorrow, with Cardinal Schönborn celebrating. This is being done at 10:00am Roman Time (which is, I believe, 6 hours ahead from Eastern Standard Time in North America). Apparently this Mass will be broadcast live on Vatican Radio.
Further, the Cantori Gregoriani are chanting Mass at Sant'Abbondio in Cremona at 11:00am Roman time, and this will be broadcast on RAI Uno.
