Dont wanna blow my own trumpet (well , I sorta do , but thats another story lol) , but you might want to check my "Babylon Falls (Horsemouth Hard Stepper) out here on RDW.
LOADS of steppers stuff coming from UK , most of which has been mentioned in this thread ( new skool-digi-dub styles) , especially Disciples , iration steppas , Earthquake (NOT King earthquake soundsystem but earthquake /TNT roots) etc etc..also the Blackamix label has pressed some great ones over the last 10 years or so like King Davids Melody (I think) and caribou cargo etc.
And as El Bib pointed out , there's a whole Steppers section right here at RDW ( check out Messian Dread's riddim of the Spiritual Warrior while you're there
) Think he's on here as Me Zion Dread.
anyway.. happy hunting
