There are no entrancing guitar riffs from The Edge here. No percussion barrage from Larry Mullen Jr. Just a reflective ode to the one and only Martin Luther King, Jr. from Bono. It flies in the face of everything that we see happening in the world - not just musically, but thematically. The Unforgettable Fire had quite a few unforgettable songs, but “MLK”, as the final track on the album, quietly and thoughtfully grabbed our attention and conscience in the most understated way.
