It was the autumn of the year 2000 when Equinox took his first music lesson with his highly regarded teacher Robbert van Sterkenburg. Equinox kept having these music lessons for over nie years; at first he was taught playing keyboard and later on he was introduced to the piano.
At secundary school he got to know an exceptionally musical guitar player with the stage name of "Mysterious Musician". It didn't take a long time to find out that not only their experience as musicians matched, but the sound of their voices as well. So since 2009 they have played at several small stages, which wasn't solely a succes for themselves, but also for the audience. This led to them deciding to go beyond being casual performers. Since june 2011 Equinox and Mysterious Musician have been performing under the name of 'Dualisten'
