Who is Joe Hahn

Joe Hahn, often credited as Mr. Hahn, is a Korean American director and musician best known as the turntablist for the American band Linkin Park. Hahn joined Linkin Park (then called Xero) in 1996 as the band's DJ. Since then, he has directed music videos for most singles of his band, with the exceptions of "One Step Closer", "Crawling" and "Faint". He is referenced to as Mr. Hahn at the beginning of "Cure for the Itch" from "Hybrid Theory". He has also directed videos for Static-X, Story of the Year, Xzibit, X-ecutioners and Alkaline Trio.

In 2005 to 2006, while bandmates Chester Bennington and Mike Shinoda were busy with side projects, Hahn shot a short film called The Seed in Los Angeles, California and has premiered it at the Pusan International Film Festival. Hahn also appeared with a minor role in a short film by Filip Engström called Little Pony. In 2005, Hahn opened a retail concept store and brand Suru, located on the infamous Melrose Avenue in Los Angeles.

Hahn was also featured on the Fort Minor songs "Slip Out the Back" and "Move On" (a Fort Minor Militia exclusive), tracks produced by his Linkin Park bandmate Shinoda. In both tracks, Hahn does some scratching in the outro.

On the new album Minutes to Midnight, Joe Hahn contributes more to programming with his sound effects board. The only songs he uses turntables in Minutes To Midnight are the minor roles in "What I've Done," "In Pieces," and "The Little Things Give You Away."

Joe also uses MIDI pads in some Linkin Park songs like "In the End", "Crawling" and "Numb"
