@living bate: yes, I think kenyatta hill continues with the project, there are some videos of him in youtube.
and there is a 2013 interview in berlin, with original member albert "ralph" walker and telford nelson (who sings harmonies in the group since 2001)
http://www.youtube.com/watch?v=85gBd3PBk8Iin the video, he starts the show with a ziggy song (message) over the natural mystic riddim...
not the same vibes, i suppose, but It would be nice to see him, just to remember & dance to some culture music live.
