Full screen/minimalised web design from load

So I'm currently building a radio player purely for mobile web browsing (a unique version a better UX experience). However I seem to be drawing to a dead end on this part of the design brief..

Can you get Safari and others to display full screen from the original load? I know it's possible once you're scrolling away, but I'm talking about having everything minimalised (even better full screen) from the second it loads. Having a chunky url bar and page control options scattered over the design is ruining the experience.

Thanks.
