Madison Avenue is a north-south avenue in the borough of Manhattan in New York City, United States, that carries northbound one-way traffic. It runs from Madison Square (at 23rd Street) to the Madison Avenue Bridge at 138th Street. In doing so, it passes through Midtown, the Upper East Side (including Carnegie Hill), Spanish Harlem, and Harlem. It is named after and arises from Madison Square, which is itself named after James Madison, the fourth President of the United States. Since the 1920s, the street's name has been synonymous with the American advertising industry.

Madison Avenue was not part of the original New York City street grid established in the Commissioners' Plan of 1811, and was carved between Park Avenue (formerly Fourth) and Fifth Avenue in 1836, due to the effort of lawyer and real estate developer Samuel B. Ruggles, a graduate of Yale University who had previously purchased and developed New York's Gramercy Park in 1831, who was in part responsible for the development of Union Square, and who also named Lexington Avenue.

Armin van Buuren (Dutch pronunciation: [ˈɑr.mɪn vɑn ˈby.rə(n)]), OON (born 25 December 1976 in Leiden, Netherlands) is a Dutch trance producer and DJ. Between 2007 and 2010, he was voted number one in DJ Magazine's annual top 100 list of the most popular DJs. In the 2011 list, he ranked in second place. Since 2001, Van Buuren has hosted a weekly radio show called A State of Trance, which claims to have around 15 million weekly listeners in 26 countries, which would make it one of the most listened-to radio shows in the world. His 2008 studio album, Imagine, entered the Dutch album chart at #1, a first for a dance music artist in Dutch music history.

Armin van Buuren was born in Leiden, Netherlands on 25 December 1976, but grew up in Koudekerk aan den Rijn. Van Buuren started making music when he was 14.^{[citation needed]} He was inspired by French electronic music composer, Jean Michel Jarre, and wished to become a great electronic music composer like Jarre.^{[citation needed]}

He finished high school at the Stedelijk Gymnasium Leiden in 1995, and left for college to study law at Leiden University. While studying law, Van Buuren's interest for making music blossomed, and he began working as a DJ in a local club called Nexus. As his musical career began to take off, he put his law degree on hold, although he did return to finish law school in 2003.

Safri Duo is a Danish percussion duo composed of Uffe Savery (born April 5, 1966) and Morten Friis (born August 21, 1968). Initially classically oriented, by 1999 they were discovered by a label executive working on classical music. After being signed, a track mixing both tribal sound and modern electronica was set to be released in 2000. The result was the popular "Played-A-Live (The Bongo Song)", that became one of the most popular songs in Europe in 2001. The single and subsequent album, Episode II each sold one million units worldwide, making Safri Duo the most internationally successful Danish act since Aqua.

Uffe Savery and Morten Friis met in 1977 while attending the Tivoli Garden Boys' Guard, and later, during their time at the Royal Danish Conservatory of Music, formed an experimental duo, called Safri Duo, whose name originated from the first letters of their respective surnames. Several albums were recorded and released through Chandos Records, on which the duo performed pieces by both famous classical (a.o. Bach, Mendelssohn, Ravel, whose works were arranged by Savery and Friis for two marimbas, or for marimba and vibraphone) and contemporary composers (a.o. Reich, Nørgård, Ter Veldhuis). Their performances of, especially, Ter Veldhuis' Goldrush, Ravel's Alborada del gracioso and Anders Koppel's Toccata for vibraphone and marimba are often labelled as small milestones by fellow percussionists^{[citation needed]}, as well as other musicians or people related to the world of classical music.
