Combining deep, solemn male choirs with mystic percussion does indeed translate into a musical pilgrimage. This is a very relaxing song, best listened with eyes closed. The melody goes through several transformations, but keeps to an overall oriental feel.
You can listen to the melody for free, in good quality, on BandCamp, which is one of the best websites when it comes to supporting artists. You can also purchase the song (or album) from this same location. And in case you’re wondering, yes, I did purchase Terry Oldfield’s album :).

Unfortunately, no YouTube version is available for this song, but that’s OK because you can listen it for free on BandCamp.
