Watch: Beyoncé performs ‘1+1’ on HBO miniseries...

When Beyoncé isn't actively executing high octane choreography, she relies solely on her amazing vocals, flowing locks and wind machines to deliver something intense and stirring for '1+1.'

The seventh installment of her HBO special X10 sees the singer twisting and writhing atop a grand piano in a bedazzling glittery blue catsuit. Watch her performance of the hearty ballad from her 'Mrs Carter' world tour below.
