This is a wonderful album and absolute perfection from beginning to end and the extra tracks are a nice addition as well.  The original Wailers were such an influential band and one of the precious few who while changing the music scene also managed to change culture as a whole.  I've always thought Mr. Marley was the truest poet in music due to the fact that he lived every song he ever wrote as did his primary co-songwriters, Peter Tosh and Bunny Wailer.  Their music and lyrical content stired up revolution both in their country, in music and in the hearts and minds of people around the globe.  This is one band that still generates a tremendous buzz today years after the release of this fantastic album.
