Have you ever considered joining DFTBA Records? Why do they not have any Wrockers signed?
They've signed Matt Maggiacomo, the muggle music of The Whomping Willows along with Luke Conard (Ministry of Magic), ALL CAPS (The Parselmouths and Ministry of Magic), The Oceanic Six (Ministry of Magic and The Remus Lupins), Kristina Horner (The Parselmouths), The Caulden Road (Oliver Boyd and the Remembralls), and Skyway Flyer (Ministry of Magic). Hank Green has also released a lot of awesome wizard rock music, and he helped to start DFTBA.
Wizard rock, since it began, has always been a completely do-it-yourself operation. It's one of the best and most unique things about the community in my opinion. And that's why I'm glad that DFTBA has signed muggle projects of wizard rock bands and not the wizard rock bands themselves. As for why they choose to do that, I'm not the person to ask.
