These are the two albums I listen to over and over again.
Durufle Requiem (Robert Shaw Atlanta SO version) – some of the best classical choral arrangements, there is so much going on that it keeps things fresh.
A Hidden Wholeness by Luke Brindley – This is an album for orphaned believers if there ever was one. You really have to pay attention to the lyrics to get the full effect of this album. A Christian site gave it a good review. It’s not a Christian album, it’s not a non Christian album, it’s kind of somewhere in the nether regions between the two. Ultimately it’s about struggling through life without giving up hope, something I do not practice in my own life.
