While it may be one of the more slow and somewhat dispiriting tracks from second album 'Neon Bible', 'Intervention' is a stunning piece and a musical marvel. Lyrically, it's almost painful, speaking of the ultimate loss of friendship and love for the sake of survival in a wholly unforgiving world, and Win Butler's vocals sound drier and most desperate than even. It serves as the band's own scathing social commentary, their own take on politics and religion in today's culture. Backed almost solely by a poignant pipe organ, 'Intervention' harbors a feeling of helpless abandon and excruciating redemption, but is gut-wrenchingly beautiful and one of the most matter-of-fact and expressive tracks Arcade Fire have ever written.
