Arvo Part... Where have you been my whole life?

My interest in classical music didn't really develop until about five years ago, so I'm still a novice compared to many of the folks here on A'gon. I tend to listen to a lot of small scale chamber music and choral music.

I've had Part's Tabula Rasa for years and always liked it, but for some reason I never delved further. I guess it's because I tend to avoid modern classical. In any case, I just started listening to some of his other works -- Te Deum, De Profundis, Alina, Litany. They are beautiful.

Can anyone recommend other works, either by Part or by similar composers? Thanks.
