Part's music so often seems to inhabit a place, take the listener to a place, beyond words. He exposes the limitation of language, when attempting to describe a numinous place, which just IS, and in the act of describing it, one is no longer inhabiting that place.
So, really, if something you want from music is to be in touch with `thoughts that do lie too deep for tears', for an experience of something ineffable, transcendent, sacred, truthful, entering into mystery, well, play the opening track. The choir, the venue with its acoustics, the music itself; these are all very special. This is tender, compassionate music, full of sorrow and yearning, but reaching beyond that to places of resolution. The silent spaces, the pauses in the music are also `full'
These are quiet, deeply felt songs of praise and devotion. Personally, I find those tracks which find that place, whilst containing pain and sorrow (such as Te Deum) more profound than pieces which are less emotionally complex, such as Credo, which are beautiful, but don't quite engage with this listener on such a completely profound level
