King's address is one of three samples of notable speeches by American political figures on A Thousand Suns
. The other two audio quotes are by workers rights activist Mario Savio (on Wretches and Kings
) and the father of the atom bomb Robert Oppenheimer (on The Radiance ). Vocalist and co-producer Mike Shinoda explained to NME
: "I just felt in all three cases, those speeches when you hear them now, resonate in a way very differently from when they were first delivered. But they apply to things that are going on today."
