Question: Remment Lucas "Rem" Koolhaas (Dutch pronunciation: [rem ko:lha:s]; born 17 November 1944) is a Dutch architect, architectural theorist, urbanist and Professor in Practice of Architecture and Urban Design at the Graduate School of Design at Harvard University. Koolhaas studied at the Architectural Association School of Architecture in London and at Cornell University in Ithaca, New York. Koolhaas is the founding partner of OMA, and of its research-oriented counterpart AMO based in Rotterdam, the Netherlands. In 2005, he co-founded Volume Magazine together with Mark Wigley and Ole Bouman.

Following the signing of Treaties of Nice in May 2001, which made Brussels the de facto capital of the European Union, the then President of the European Commission, Romano Prodi and the Belgian Prime Minister Guy Verhofstadt invited Koolhaas to discuss the necessities and requirements of a European capital. During these talks and as an impetus for further discussion, Koolhaas and his think-tank AMO - an independent part of OMA - suggested the development of a visual language. This idea inspired a series of drawings and drafts, including the "Barcode". The barcode seeks to unite the flags of the EU member countries into a single, colourful symbol. In the current European flag, there is a fixed number of stars. In the barcode however, new Member States of the EU can be added without space constraints. Originally, the barcode displayed 15 EU countries. In 2004, the symbol was adapted to include the ten new Member States. Since the time of the first drafts of the barcode it has very rarely been officially used by commercial or political institutions. During the Austrian EU Presidency 2006, it was officially used for the first time. The logo was used for the EU information campaign, but was very negatively criticized. In addition to the initial uproar caused by the Estonian flag stripes being displayed incorrectly, the proposed flag failed to achieve its main objective as a symbol. Critics pointed the lack of capability to relate the signified (the mental concept, the European Union) with the signifier (the physical image, the stripes) as the major problem, as well as the presented justification for the order in which the color stripes were displayed (as every country in the EU should be regarded as equal in importance and priority).

Question: Snow Patrol are a Northern Irish rock band formed in 1993, consisting of Gary Lightbody (vocals, guitar), Nathan Connolly (guitar, backing vocals), Paul Wilson (bass guitar, backing vocals), Jonny Quinn (drums), and Johnny McDaid (piano, guitar, backing vocals). Initially an indie rock band, the band rose to prominence in the early-mid 2000s as part of the post-Britpop movement. The band were founded at the University of Dundee in 1993 by Lightbody, Michael Morrison, and Mark McClelland as Shrug. After briefly using the name Polarbear and released the EP Starfighter Pilot (1997) and losing Morrison as a member, the band became Snow Patrol in 1997 and added Quinn to its line-up.

In 2002, the band started to be managed and published by Jazz Summers of Big Life. Guitarist Nathan Connolly, previously a member of the band File Under Easy Listening had been working in an HMV store room in Belfast at the time. Connolly and the band had a mutual friend, who introduced them to him. Connolly moved to Glasgow to join the band in the spring of 2002. During Lightbody and McClelland's years at the University of Dundee, they had been noticed by Richard Smernicki, a senior student. Through Richard, brother Paul too had come to know the band. Richard graduated in 1996, two years before Lightbody and McClelland, to become Polydor's Scottish A&R representative. Paul became Polydor's Press and Artist Development Manager and Fiction's label manager. Later, Jim Chancellor, an A&R executive for Fiction, and fellow talent scout Alex Close approached the band in Glasgow to listen to their demos, and judged them on "the quality of the songs", according to Lightbody. Chancellor introduced them to producer Jacknife Lee, who despite having been a guitarist in 90s punk rock band Compulsion had no rock production experience at that point, being known at the time for his work with Basement Jaxx and Eminem. Final Straw was released on 4 August 2003, under Black Lion, a subsidiary of Polydor Records. Its music was along the same lines as the band's first two albums, and no attempt was made to change the sound to something more radio-friendly. The album, along with "Run" (which debuted at No. 5 in the UK Singles Chart), gave the band their first taste of mainstream success. The record peaked at No. 3 in the UK Albums Chart. They followed the success of "Run" up with three more singles from the album: "Chocolate", as well as a re-release of "Spitting Games", both reaching the top 30, and "How to Be Dead" reaching number 39. The release of Final Straw in the United States in 2004 saw the album sell more than 250,000 copies and become the 26th most popular album in the UK of that year. In mid-2005, during their tour to support Final Straw, the band toured with U2 as an opening act on U2's Vertigo Tour in Europe. The band then returned to the United States to continue touring in support of Final Straw. That summer also saw Snow Patrol playing a short set in London at the worldwide benefit concert Live 8. After finishing their opening act duties and extensive 2-year tour of Final Straw in late July, the band took a few weeks off and began writing and recording songs for a new album. Snow Patrol's new version of John Lennon's "Isolation" was released on 10 December 2005 as part of the Amnesty International campaign, Make Some Noise. The song was later issued on the 2007 John Lennon tribute album, Instant Karma: The Amnesty International Campaign to Save Darfur.
