Watch Katy Perry Debut “By The Grace Of God” & Perform More ‘Prism’ Tracks At iTunes Festival

Katy Perry closed out this year’s iTunes Festival in London Monday night (September 30) with a set that included her hits as well as four Prism tracks. Rocking pigtails and a punky plaid outfit, Perry started things off with her latest single, house thumper “Walking On Air.” Before finishing with “Roar,” she worked her way through “Dark Horse” (which she introduced as one of her favorite songs) and debuted the previously unheard ballad “By The Grace Of God.”

For the new song, Perry was accompanied by a piano and a couple backup singers, and it’s a nice counterpart to “Roar” — both are about rising up and conquering in the face of adversity, but this one interprets the message through more intimate, specific imagery, as she sheds light on the emotional turmoil she suffered after divorcing Russell Brand, and the help her sister provided.

Check out “By The Grace Of God” up top, and head below to see the other three Prism performances.
