Julio Iglesias (born Julio José Iglesias de la Cueva; September 23, 1943) is a Spanish singer and songwriter whose romantic image, magnetic stage presence, and expressive music made him one of the best-selling artists of all time. By the early 21st century he had sold hundreds of millions of albums in more than a dozen languages. He has sold over 300 million records worldwide in 14 languages and released 77 albums. According to Sony Music Entertainment, he is one of the top 15 best-selling music artists in history. While Iglesias rose to international prominence in the 1970s and 1980s as a performer of romantic ballads, his success has continued on as he entered new musical endeavors. He is the father of singer Enrique Iglesias.

Iglesias was born in Madrid, the eldest son of Dr. Julio Iglesias Puga and María del Rosario de la Cueva y Perignat. Iglesias' father's family was from Galicia, and Iglesias' mother an Andalusian.

In the 1960s, he studied law in Madrid and was a goalkeeper for one of Real Madrid's football teams. On September 22, 1963, he was involved in a car crash, resulting in an injury to his spinal cord. He said, "I had a car accident; [a] very, very strange car accident...I lost control of the car and rolled it, resulting in what they call 'paraparexia,' which is not paraplegia. It's a compression in the [spinal] cord, in the sense of the neck...my spinal cord; and I was very, very ill for three years."  His doctors thought he would never walk again; indeed, his legs were left permanently weakened, and they continued to require therapy as of late October 2010. However, slowly, he began recovering his health. To develop and increase the dexterity of his hands, he began playing guitar. When he recovered from his accident, he resumed academic studies and traveled to the United Kingdom to study the English language, first in Ramsgate, then at Bell Educational Trust's Language School in Cambridge.

The Cataracs are an American hip hop indie-pop duo formed in Berkeley, California, consisting of David “Campa” Benjamin Singer-Vine, a songwriter and vocalist and Niles “Cyrano” Hollowell-Dhar, a songwriter, vocalist, and producer. The duo started out as an independent group, during their years at Berkeley High School. The two were first signed to the label Indie-Pop. They are currently based in Los Angeles, California.

The duo met in their sophomore year while attending Berkeley High School. Singer-Vine was featured in a rap CD that was being passed around campus. When Dhar eventually heard the CD, he subsequently created a response. However, the “diss” response brought the two together and they soon became friends. In 2003, the two joined together to create what is now The Cataracs (named after the phrase “Who smoke ‘til your eyes get cataracts” from Snoop Dogg's song “What's my name Pt. 2”). In the summer of 2006, they released their first album, Technohop Vol. 1. In August 2006, the group joined with The Pack to make the single “Blueberry Afghani”. The song soon became a hit and was chosen as a “Download of the Week” by 106 KMEL and many music sites such as The Fader, UK’s Hip Hop Connection and XLR8R praised it.
