to Kevin: yes, the recordings of 'Uhuru in Dub' are on the GS double set GRE2051 (and have been released as artist Sly & Robbie on CD (CSA CD 100) way back in 1987. I apologize if impressions appear that this is 'rare'. Thre mastering of the CD in this box-set is better than before, the sound is minimum slightly better.
and to all: I think the Vol.7 will not make it to be the Scientist one (for law suit reasons - see old forum contributions - and even there are alone two Volumes for Scientist as minimum alone necessary

- I've been told that there is a complete 'Junjo' Lawes productions unreleased album by Scientist in the archives, but can't be released)
to informer: For sure I agree that this series is 'nothing for real' without Augustus Pablo (very expensive to realise) and Lee Perry (even more expensive

.
Please don't forget that this series is mainly for the real young people, the 'internet generation' - even with an attractive price it's not that easy to get them 'on board' - they don't have a clue for the original versions to compare with, that don't count for them - 'it's massive sound ot nothing' - (don't forget the bass sound of Dusstep) - four albums for the price a little more than one full price CD is pretty cool, and not to forget the booklet notes are the ones for Roots Archives members

.
And to come back to the subject - Prince Jammy wasn't an astronaut - he was a pupil of King Tubby!
I try to enforce the makers of this series as hard as I can that the series shouldn't be limited to seven volumes, better to 70 volumes

- any help in contacting labels & producers is much appreciated.
