That's pretty good. It's one of those records that a lot of people rave about just because Lee Perry produced it, but to me it's just kind of everyday 1977 era reggae. Which is a good thing, and a time that can't be repeated (well, no time can be repeated, can it?), but the songs are just kind of okay.
That's the original Perry mix in that video, which no one really heard until a 40th anniversary version came out a couple years ago. Before that the original mix was only available on the first 200 copies of the album that were pressed. Which made it, you know, slightly difficult to put your hands on a copy.
