Atmospheric English indie pop group  The xx formed in London around the talents of Romy Madley Croft , Oliver Sim and Jamie Smith, when the band members were still in high school.

Captivating and cool the group cites influences that run the gamut from R&B to classic alternative rock. 

Built around the duel vocals of Romy and Oliver, the group's signature brand of moody, soulful indie rock first appeared on the public radar in early 2009 with the single "Crystalised", which created a huge buzz among critics and fans alike.
