Arvo Pärt

I have been listening to Fratres and Tabula Rasa a lot lately and am wondering if anyone has suggestions for good performances and recordings of these pieces. I really like the Gothenburg Symphony Orchestra conducted by Neeme Järvi, I have another version of Fratres conducted by Andrew Parrot and while I like his vocal work with Pärt I do not care for his lack luster interpretation of Fratres. I have heard from people that the Naxos recordings of this work is pretty good, any thoughts on that, or other recommendations? I feel John Tavener's Out of the Night vocal music is similar to Pärt's Magnificat- are there any other composers who seem to capture the mystisism as well as Pärt instrumentally? Thanks for any insight!
