Jamie Smith (from The XX) or known by his stage name Jamie XX. He is an English music producer and remix artist if you will. His proffessional musical career started when he joined The XX. I recently heard his remix from Jack Penate - Pull My Heart Away. Seriously an amazing artist. I saw The XX at Coachella back in 2010 and had no idea one of the band member is INSANELY awesome. There is a strong rumor that Jamie XX is going to be playing at Coachella 2012, and I for one hope this rumor is true because I would LOVE to hear his tunes live & loud. Also I suggest listening to his remix of Radiohead - Blom.
