is a German rapper signed to the German music label Four Music. Casper was born in Extertal in North Rhine-Westphalia to a German mother and an American father, Arlen Griffey, who was a soldier stationed in Extertal. His family moved to Augusta, Georgia, in the United States, when he was two weeks old, where he lived in a trailerpark. At the age of 11, he moved back to Germany with his mother and younger sister. Despite his mother being German, he had not been raised bilingually and therefore struggled at school initially. Casper was involved in many studio recordings with other German rappers, such as Abroo and Separate. Together they founded the hip-hop group Kinder des Zorns. In 2004 they released Rap Art War, their first and only album. In 2006 he released a mixtape called Die Welt Hört Mich with the label 667 - On More Than The Devil. In the two years following the release of Die Welt Hört Mich, he toured through Germany and on 9 May 2008 he released his first album, Hin Zur Sonne with the 667 record label. In February 2009, he left 667 Records and signed a contract with Selfmade Records. Together with Kollegah, Favorite and Shiml, who were also signed to Selfmade Records, they released Chronik 2 in April 2009. In October 2010 Casper left Selfmade Records and signed a new contract with Four Music. His second album, XOXO, was released on 8 July 2011. Casper is known for his slightly hoarse sounding voice: this was as a result of him having played in punk/hardcore bands in the early days of his music career which resulted in some damage to his vocal cords.
