     Grammy nominated (格莱美奖提名) artist and globally admired DJ and Producer Paul van Dyk

continues to lead the electronic music charts and appears at the highpoint of every Top DJ list across the

globe.PvD, as his fans have nicknamed him, is currently ranked the World's No.1 DJ by DJ Magazine's

"Top 100 DJs poll" for the second successive year.

     PvD is wellknown as one of the hardest working artists, with soldout tours that cross each continent,

headline spots at every major festival, and a hugely successful recording career.With over 3 million albums sold worldwide, van Dyk travels around the world over 16 times each year to sold out performances

internationally.

     Born in Eisenhuettenstadt, East Germany, Paul van Dyk grew up in East Berlin.Because his community did not have a true club culture, Paul van Dyk listened to the radio where he discovered his passion for

music that extended beyond Techno music-he wanted to create a different, more unique sound.In the early 1990's Paul van Dyk was performing regularly at various clubs in Berlin before releasing his first album

45 RPM in 1994.But it was the release of his second album Seven Ways that put him into Top 100,

followed by the release of his hit single "For An Angel, " which began to earn him praise across the globe.By the time Paul van Dyk released Out There & Back in 2000, it became clear that the Berlinbased

musician had far more to offer than his signature club sets that had already defined him as one of the most

influential DJs and producers of all time.His first mix CD Politics of Dancing was released in 2001,

followed by Global in 2003-a DVD which illustrates his own experiences traveling the world.
