This is today's recipe for a delicious mashup: Add a dash of Florence and the Machine's "Shake It Out" to Taylor Swift's "Shake It Off." Shake them together. Garnish with vocals from Evynne Hollens. Serve fresh. Hollens calls this dish "Shake It Ouf."
It's a big day for the Hollens family because Evynne's husband, Peter, also unleashed a haunting a cappella cover of Gary Jules' "Mad World." And if you're wondering, yes, the married couple does do duets.
