2013 collection of remixed tracks from Björk's critically-lauded 2011 album Biophilia. Bastards includes some of the remixes released in an eight-part series earlier this year, remastered for this album by Grammy-nominee Mandy Parnell, and features collaborations with Current Value, Death Grips, Hudson Mohawk, Alva Noto, Matthew Herbert, Omar Souleyman, 16-bit, These New Puritans, and the Slips. Björk also worked with her sound engineer Curver Thoroddsen to isolate a specific chapter of Matthew Herbert's Sacrifice' remix on the Pins & Needles' Mix found on the album.
