Deluxe two CD edition contains bonus disc with two additional tracks. With his 2016 album, Are You Serious, Andrew Bird has widened the breadth of his art by directly reflecting his own human experience. With key contributions from Fiona Apple and Blake Mills, Are You Serious attains a level of expression that's a personal, evolutionary leap. Are You Serious is the second record Bird has made with producer Tony Berg, following 2005's breakthrough The Mysterious Production of Eggs. Andrew Bird was initially known through his work with the band Squirrel Nut Zippers before forming Bowl of Fire, and is now best known as a solo musician. Bird's primary instrument is the violin, but he is also proficient at various other instruments including the guitar, the mandolin, the xylophone, whistling, and the glockenspiel.
