Come O Spirit! An Anthology of Hymns and Spiritual Songs is a beautiful compilation CD put out by Bifrost Arts. According to their MySpace profile, Bifrost is "a sacred music non-profit that exists to enrich the church and engage the world with beauty and truth."
The info I've found about them online is a little patchy at best. It seems like they are trying to provide music that encourages congregational singing in the church. This really appeals to me. The quality of their music is very high, and it seems that good lyrics are a priority. They include many old hymns with new arrangements, but also some new songs.
On a side note, the Kyrie on this album is beautiful, but a little too Roman Catholic for me. I'm a big advocate of church music being in the vernacular so that everyone can understand what they are saying. But apart from this, I love the album. I think the sign of a good album is when it gets better the more you listen to it. And this one does.
The Christmas album is a little darker then your average, but gorgeous in it's own way. Christianity Today says of it, "Think Tim Burton's Nightmare Before Christmas with the life-changing message of peace on earth, goodwill to men." My Kids don't like it as much as I do. When I was listening to Let All Mortal Flesh Keep Silence, my two year old said, "Mommy, I'm scared!"
I bought my albums on itunes for $9.99 each, but it looks like you can also order them from Amazon.
They have started a blog here, and some interesting reviews here and here.
