I like most of what the Celtic Woman puts out
Celtic Woman - Fields Of Gold (I have a sweet spot for that tune) but this is a great cover

Lisa Gerrard - Now We Are Free
http://www.youtube.com/watch?v=vHAvjaHtlMA
Secret Garden - a Norwegian, Celtic Duet, he composes and plays the piano, she sings and playes the violin
They often invite other singers to sing the lead. Barbra Streisand sang one one track in their last album.
You Raise Me Up - Secret Garden feat. Brian Kennedy (The original and I think the best version)

If you get a chance listen to Celtic Roots I do not know who produced it. I picked it up a decade or so ago. The CD is long gone. Thank god I ripped it!
Just to throw in one up and coming pop singer
Will Martin sings Going Home (not his best but the best I could find on Youtube) My favorite is Into the West which he recorded in his teens.
