It is not a long time ago since The National performed their song, " Start a War" with Win Butler, the front man of Arcade Fire at UCI Pavilion in Chicago on April 25th. This time, the band collaborated with Owen Pallet for a song called " Exile Vilify" at the Bryce Dessner-led MusicNOW concert last week. Pallet showcased his amazing violin skill with the beautiful song along with the trumpet and trombone. Enjoy!!!
