From the Baltimore Sun: 
It takes a little time to unroll “Scroll,” a composition by Baltimore composer Will Redman, since it’s on paper that measures 8 feet long, 8 inches wide. It takes even longer to digest.
Although there are four distinct lines of music on the elongated page, indicating at least four players, there’s no specification of instruments.
So how do you perform such a piece? Ask Redman and he’ll just say: “That’s up to you.”
