It's a "showcase" style set with Tristan Palmer vocals followed by Jah Thomas toasts - they aren't true "discomixes," though, and sometimes the rhythm track underlying the Thomas toast is somewhat different than that used for the Palmer vocal (occasionally this is disappointing; the wicked "Shank I Shek" rhythm under Tristan's "Young Lover" isn't used for Thomas's toast, for example). In terms of musical quality, the set is solid: mostly a consistant "good/OK" level, with a few standout tracks and several more mediocre ones. I don't remember any of it being really unlistenable. If you like Jah Thomas productions (I do, just so you're warned) then you definately should pick it up; if you're sick of Radics recuts of the usual rhythms then you should probably skip it.
What about the half that's never been told?
