606 ( The Blind Boys of Alabama - Amazing Grace )

This song has been running through my mind off and on the last couple of days; and I absolutely love this song. This rendition of Amazing Grace is set to the tune of "House of the Rising Sun," however with the power that these gentlemen inject into the song, they make it their own. Their vocals are so powerful and mindblowing, just so much soul here. One of the aspects that really made this song so appealing to the ear is their use of symmetry in the song to effortlessly build it up and bring it back down.

Here is a fan video with the studio version on YouTube.
Here is a rather nice live performance on YouTube.
