This is the only excerpt I could find on Youtube involving the infamous 'Chalice Scene' from the Soul Syndicate documentary "Word Sound and Power". This is one of the finest and realest films I've seen yet to document the Jamaican Dub experience, via the Soul Syndicate band in particular. Highly recommend it for any fans of Jamaican music culture, Dub and Reggae. And especially those interested in the 70s-era Dub Reggae scene in JA.
Oh, and kids - don't try this at home!
Order the DVD direct from it's producers at http://www.wordsoundandpower.com/. You will not be disappointed.
