Holy shit- didn't realize that Dylan had put all *his* stuff on YouTube. Definitely a few releases of his I need to catch up on, mostly bootleg series stuff.
"Conquering Lion" is included in full on the "Jesus Dread" comp- which is the best Yabby release by far IMO- so if you have that one, you've basically heard it. And yeah, his discography is even more convoluted than Scratch's but he's my 2nd favorite reggae artist after Perry so definitely worth sifting through it. A little overlap but the "Dread Prophecy" comp is also really ####in good.
Think you might have recommended Zukie in the past but I'm not familiar with him or McGregor so I'll add those both to my "to listen" list.
