If you haven't checked out this record you are truely missing out on one of the best roots reggae records of the century. Some of this band's later material was a little hit and miss, but there is seriously not a bad track on this particular record. A pure classic in my mind. This one gets regular rotation from me amongst all the other reggae I listen to.
Here's a couple links to some tunes off that record on youtube.
