Diving into this = drowning.
I simply don't know where to begin w/Yabby You. Too much. There's like 19 Pressure Sound 2xLP comps.
For Keith Hudson, Studio Kinda Cloudy and especially Flesh Of My Skin Blood Of My Blood both top Pick A Dub. Just my baldhead opinion.
Last legit great reggae LP I happened upon was Little Roy's Tribal War. Recent reissue available still. Excellent.
Into the 80s...all hail Wackie's, though the price points render most unobtanium. Lovejoys, Horace Andy's Dance Hall Style (hell, all Horace Andy) and the myriad dubs/collections are mostly insane.
Most enduring obsessions for me have been Prince Far I and Dennis Bovell. For the punks.
