Trent Reznor isn't known for his sunny disposition, and following this year's Grammy Awards performance took to Twitter to criticise the organisers for cutting off his performance with Dave Grohl, Josh Homme and Lindsey Buckingham.
In 2013, at Reading Festival he publicly criticised the festival and national treasures, Biffy Clyro - before he performed at the event. Reznor is traditionally a prickly individual, never afraid to share his opinions or smash up a stage if things aren't to his liking.
