The debut took place at Kyiv's Art Club 44-B. My good friend Vasyl, of the uaMuzik blog was kind enough to interview him at the debut for me. The interview will air later this month, so stay tuned!
(There's a photo of Riffmaster and Vasyl in an earlier blog post (here) taken at the Kupidon bar when I was in Kyiv last fall.)
The song itself aired on the Feb. 22 broadcast of Nash Holos so if you haven't heard it yet, download the program and give it a listen! (It's just past the halfway mark.)
More information about Riffmaster and his music at his website (here).
