Who or what would be a good next step for me Fark?
10 ft Ganga Plant, who are kindof a JBB side project would be a logical place to go.
Midnight Landing, is one of my favourite reggae albums of all time, but their last three Midnight Landing, Bass Chalice, and Bush Rock are all fantastic modern dub and roots reggae. It's dubbier and there are far more instrumentals than JBB, but there are many of the same musicians, and accordingly a lot of influences are similar. They also bring in guest roots musicians, for instance the meditations etc.
