Career(生涯)：
Early career
Gary D. started out playing as a DJ at the age of 16 in 1980. In his first years, he mostly played Black Music. It wasn't until 1988 when Gary D. started to get more involved with electronic such as, Techno and House, which in the same year he released his first single "Ecstasy" under alias "Acid Syndrome". As a DJ, Gary D. performed quite often at a club called 'Unit Club' from 1988 up until its closure in 1994. He later moved to another club called 'Tunnel', which hosted most of the German and International events like, Mayday, Love Parade, and Energy.
As a trance producer and DJ
In 1991, Gary D. released his first trance EP, "Identity E.P." with five singles it and was released on Container Records, which he released many singles on the label before being switching to Tunnel & Bonzai Records. Under Bonzai, Gary released two well known Hard Trance anthems, "Kinetic Pressure" and "Overload".In late 1995, he and two others from PIAS Recordings Germany came up with an idea to create a trance compilation, which came out to be "D.Trance", which grew into a big success. To date, Gary D. has released more than 40 D. Trance compilations as of 2009. Which was unlikely since its debut in 1995, non-mixed compilations were not as popular as mixed ones. In response to that, Gary added a third disc, which compiled all the tracks from the first discs into one mix. In 2000, he created "D. Techno" a more harder style compilation.
Shift to Hardstyle
In 2001, Gary took a different direction with his career, and started to release more Techno, and adapt Hardstyle kind of music to his DJ sets. From 2003-2005 he played in many gigs in the Netherlands and played in large venues with up to 25,000 people. Despite all that, he still continues to compile trance music for his D.Trance compilation.
