Second Concerto for Orchestra is the Big One where all the conflicting tendencies of the time fuse and make peace; a confluence cross-copulating the total constructivistic modern, but on popular-cliché material, and embracing a wholeheartedly romantic vision of landscape / city / body metamorphosis.  It had to be dedicated to Oliver Knussen. Without his generous sharing of manifold eclectic and well-aimed stimuli — above all my first mind-blowing exposure to Amériques — this piece wouldn't be as it is (maybe wouldn't be at all). [Though I mustn't forget Carter's Concerto for Orchestra (ditto).]
