Tank (born Eric Geisenheyner on July 1, 1977, in Hamburg, Germany) is a German musician and martial artist known best as the vocalist on several hit techno songs. Born to Ghanaian parents, he was adopted by a family in Hamburg following the accidental death of his parents. He first came to prominence by winning several Karate championships in Hamburg, and eventually won a national championship.
Although he had always been an enthusiast of Progressive electronic music, it was Tank’s encounter with some DJs at a club in Hamburg, that spurred him on to consider a career in music. The producers invited him to be the vocalist on "Can U Feel The Bass", which was still in production at this time. He accepted the invitation, and the song went on to become a hit in 1997. The following year, they teamed up again to release another club track entitled "The Return Of Power", whose music video was shot in London.
