Martin Planning Country/hip-Hop Album
The 28-year-old says, "Country is a very sleeping beast within us. We have two things we're not allowed to do - country and rap - just because of where we're from.
"So I think they'll rear their heads at some point in the future. In fact, I think the only future for music is if you bring together the most disparate worlds.
"That would be an album between Garth Brooks, Coldplay and Kanye West and produced by Timbaland."
