German DJ/producer duo that consists of brothers Dirk & Marco Duderstadt. Best known for their 1999 hit single "Toca Me", which they produced under the alias "Fragma". "Toca Me" was later combined with Coco Star's "I Need a Miracle" to form the vocal trance anthem "Toca's Miracle".

The brothers operate under 3 aliases:
They produce Uplifting Trance under the Duderstadt alias, Commerical Trance/House under the Fragma alias and they also work under the name Inpetto, which, although a few original songs were made under this name, is mainly used for remixing their own work.
