This isn’t something we usually do here at ManagingCommunities.com, but it’s kind of a unique situation. Ryan Leslie, a singer, music producer, entrepreneur and more, was kind enough to provide some advance praise for the book. And he just released his first music video. It’s for “Diamond Girl”, a track that is already charting on the Billboard Hot 100 (i.e. the most important music singles chart). I like the song a lot. So, please check out the video below.
