Dave Simonett has strayed away from Trampled By Turtles in the past, mostly via his side project Dead Man Winter. But Red Tail, out March 13 and premiering exclusively on Billboard one day early (March 12), marks the first time Simonett has stepped out under his own name -- a prospect that became more palatable over time."Dead Man Winter was supposed to be, in my mind, an umbrella for all my solo work, but as it's progressed it's become a band in itself," Simonett tells Billboard.
