Death Grips no longer on Pitchfork Fest, or opening for Soundgarden & NIN (or on any show)

Death Grips broke up today and cancelled shows, including Fun Fun Fun Fest (who responded) and Pitchfork Fest who have yet to officially respond or announce a replacement. Who should they get?

Death Grips were also set to open the Nine Inch Nails and Soundgarden tour which hits Tinley Park, IL's First Midwest Bank Amphitheatre on July 24. Trent Reznor is not sure why he bothered giving them a chance.
