Having graduated as a Bachelor in 1982, Margret followed her love of music by playing bass guitar
and working voluntarily at gigs so she could learn the art of music mixing.
This led to a trip to West Africa in 1984 to record a band based in Guinee-Bissau; on her return to Holland,
the recordings helped her enter the studio world.
She soon became a successful freelance engineer, working at Wisseloord
(Hilversum, The Netherlands),
Chateau du Pape (Hamburg, Germany), Red Rooster (Munich, Germany), Jet (Brussels, Belgium) and others.
During this time she worked with artists as Simple Minds, Sade, Def Leppard and Paul McCartney.
In 1998 Margret set up Hill Suite 7 Management, managing productions for the following renowned producer/engineers:
* Gareth Jones *
(Erasure, Depeche Mode, Mogwai, Liars, Grizzly Bear)
* Peter Schmidt *
(Peter Fox, Beatsteaks, Rosenstolz, Reamonn, Peter Maffay)
* Ronald Prent *
(Guano Apes, Rammstein, Manowar, Kane, Herbert Grönemeyer)
