Frederic Holyszewski

Frédéric Holyszewski (Paris, 1970), also known as Dado and Deedrah, is a French music producer mostly known for psytrance projects such as Deedrah, Transwave, and Synthetic.

Biography Holyszewski learned classical music since his childhood, playing piano and transverse flute, yet wanted to be a biology teacher. He got a master's degree in biology and geology (PARIS 6) but stopped his studies when he was 25 years old to produce music.

In 1994, with Christophe Drouillet aka Absolum, Holyszewski formed psytrance group Transwave. In 1996 they released debut album Helium, which received a 4* review in Muzik magazine. The duo made an impact on the genre, in particular for their live performances, and by 1997 had become known as "scene stalwarts". Holyszewski also composes music for PlayStation video games, for example Gran Turismo 4 in 2004 which featured two of his tracks under the "Synthetic" alias.
