One + One
Chris Cornell, of Soundgarden fame, combined the lyrics from Metallica’s song “One” with the melody from U2’s song “One” to great effect. I’m not a huge Metallica or U2 fan (more of a Soundgarden fan I suppose) but this combination is uniquely moving.
There is another video of a different performance of the song on YouTube. It has better sound quality but lacks the same emotion as the performance above.
