Author’s note: I haven’t written anything about Baltimore music (or anything for that matter) for a while, for a lot of reasons. But all the reasons added up to the worst case of writer’s block I’ve had in some time. But Kane Mayfield’s show this past Friday night put a significant crack in that block. And the next day, driving around Baltimore bumping “Return of Rap” and “Return to Sender” (a collection of Kane’s previously unreleased work that was also sold at the show), and then a long late night conversation with the man himself make the rest of my writer’s block crumble. So enjoy my return to writing by reading my review of “Return of Rap: Act II” the show as well as my review of the CD, which is why this piece is so long. But trust me, it’s worth it.
