Eric Marlon Bishop (born December 13, 1967), professionally known as Jamie Foxx, is an American actor, singer-songwriter, rapper, stand-up comedian, and talk radio host who began playing the piano when he was five years old. As an actor, his work in the film Ray earned him the Academy Award and BAFTA Award for Best Actor as well as the Golden Globe Award for Best Actor in a musical/comedy. He is also a Grammy Award winning musician, producing three albums which have charted highly on the Billboard 200: Unpredictable, which topped the chart, Best Night of My Life and Intuition.

Born in Terrell, Texas, Foxx was raised by his mother's adoptive parents. He performed in high school and was awarded with a scholarship to United States International University. In his twenties, Foxx began performing stand-up at comedy clubs, and eventually joined the cast of In Living Color in 1991; this exposure helped him land film roles and star in his own sitcom, The Jamie Foxx Show. He released his debut album, Peep This, in 1994, but he did not gain significant musical success until 2004 when he was featured in Twista's song "Slow Jamz". Also in 2004, Foxx played critically acclaimed roles in the films Collateral and Ray. He released his second album, Unpredictable, in 2005, which was helped by his collaboration on Kanye West's number-one single "Gold Digger". His third album Intuition was released in 2008 and was anchored by the single "Blame It". Foxx released his fourth studio album, Best Night of My Life, in 2010.

Adam Richard Wiles (born 17 January 1984), better known by his stage name Calvin Harris, is a Scottish DJ, singer, songwriter, and record producer. His gold-selling debut album, I Created Disco, was released in 2007 and contained the top ten singles "Acceptable in the 80s" and "The Girls". His second studio album, Ready for the Weekend (2009), reached number one in the UK Album Chart and includes the chart-topper "I'm Not Alone", the UK top five hit "Ready for the Weekend", and the singles "Flashback" and "You Used to Hold Me".

A remix album titled L.E.D. Festival was released in July 2010 as a free album in the August issue of Mixmag. Harris is currently working on his third studio album—due for release in 2012—which has produced the singles "Awooga", "Bounce", "Feel So Close", and "Let's Go". He has written and produced records for other recording artists including Kylie Minogue, Sophie Ellis-Bextor, Dizzee Rascal, Rihanna (on the international chart topper "We Found Love"), and Kesha.
