I dunno whether it's a legit version or just the way it's been uploaded, but I prefer this one in mono.
Blackboard Jungle Dub part one
must be one of the most sampled introductions to an album...
Apparently it's actually by a guy called Mike Brooks and there's an alternate mix on a Revolutionaries album/compilation called Channel One Revisited Dub. It was mistakenly released as a Lee Perry thing on an album called Blood Vapour.
And the Blackboard Jungle dub where the sound cuts out like a mini-earthquake's gone off
The Gatherers - Words
this is one those riddims where I can listen to version after version - hypnotic, dread, uplifting, spiritual vibe
