That Slaine album is good. I wish more of the production stood out, but it is a solid album.
Royce's album is nothing outstanding, but has a couple of good tracks.
That third album looks interesting, will probably look into getting that one, I really liked The Left's Gas Mask.
I've skimmed over Kendrick's previous two albums a bunch of times now, but can never bring myself to focus on them. They both sound great, expecially OD, but I'm still working on giving them a full listen.
