I have posted Ave Maria by 4 different composers (listed under Good Sites, Blogs, Web Pages... in the right margin). I am now replacing the Bach/Gounod video in the list with this version featuring Deborah Sasson, also with Andre Rieu. I think Sasson sounds a little bit more musical and polished than Skota.
I am adding this Schubert's Ave Maria sung by Mirusia Louwerse, again with Andre Rieu. Barbara Bonney, already listed, may be more pure, but Louwerse is more expressive.
