Grimes

The hyper-trendy indie-pop innovator had to abruptly cancel a string of highly anticipated tour dates in 2012 after suffering an acute acoustic trauma that left her with blinding tinnitus.

Explaining the terrifying ordeal to her massive online following on social media, Grimes revealed that the non-stop ringing was so intense it caused severe sleep deprivation, forcing her to completely rethink her stage volume and studio production habits to protect what remained of her hearing.
