Watch: Jamie xx, members of the xx perform “Loud Places” on Seth Meyers

Jamie xx, the heartbeat of the xx, broke out on his own this year with the critically acclaimed "In Colour." Monday night on "Late Night with Seth Myers", Jamie xx enlisted the support of his two bandmates, Romy Cross and Oliver Sim, to perform one of Reverb's favorite tracks of 2015, "Loud Places." The airy and emotional take also included ex-CU Boulder student and Chairlift frontwoman Caroline Polachek; Pauli and Stella Mozgawa from Warpaint; Jehnny Beth from Savages; Moses Sumney; Okay Kaya and the winner of the evening, the Harlem Gospel Choir.
