Ailee and Whee In just unveiled a special live performance clip of "Solo Christmas!" 

With a dulled yet Christmas-y backdrop, Ailee and Whee In's angelic voices warm up this cold winter with their warm angelic voices. 

Earlier in July of this year, solo artist Ailee signed on as the first artist of The L1VE, the latest music label headed by VIXX's Ravi. In August, MAMAMOO member Whee In also joined The L1VE, expanding the label's family. "Solo Christmas" is the first collaboration of these two artists. Check out the live clip above!
