What you had here was a powerful and subsequently very successful creation from the dominant Roots Reggae producer of the era, Kemar 'Flava' McGregor, which so wonderfully translated from making hit songs into being a big hit album, which is, as we've seen in over 120 instances, a pretty rare occurrence.
The Rub-A-Dub Riddim probably is still my choice as the finest edition of Riddim Driven of all time.
