The Edge has been speaking about the passing of Mark Fisher, groundbreaking stage designer, architect and friend of the band who worked with them for more than twenty years.

'Mark Fisher's vision and genius was his ability to translate dreams into reality. With his talent and passion, he created designs which never failed to push every concept to the absolute limit. He made the impossible possible. And it always looked beautiful.

'Mark was a dearly beloved member of the U2 family and we shall all miss him very much. Our thoughts and prayers are with his family.'
