John Groen is born on 21 February 1950 in The Hague
Round the age of 16 he started to drum, at first in a band called Wild Cherry, who played regularly in the Marathon (The who played there on their first tour in Holland). Later when Wild Cherry stopped he became the drummer of Lava. After this group he quit to play the drums.
It will be 1976 when he heard from Henk Brautigam the brother of Ronald that Plackband was searching for a sound engineer because they had bought a PA installation.
John thought it was a good idea not at least because he was very interested in sound and technique.
He was very handy indeed and many times you saw him crawling over the stage to repair things
Many nights he spent also with the other members of the band in tuning the Pa and testing it. In that days it was not so easy to combine PA components as nowadays.
The symphonic style fits with his adoration of bands like yes and Genesis.
To transport the PA and backline a normal delivery van was not enough so the band decided to buy a large truck. So there was another problem, nobody was licensed to drive in it. John became the trucker.
When plackband ended his first nperiod in 1981, he started a studio called Sound Design, together with the drummer Tom van der Meulen. In that studio the recordings were done for The first of November.
Also in those days the corporation with Rob Rehorst of Holland Spoor Studio started.
Although Plackband no longer existed ,the members still were close friends, so the contacts stayed alive.
Then came the reunion and John of course was present, but he was interested in a more global function, so he does, stage management, monitoring and technical support.
Together with Dammes (sound) and Rene (light) he forms a dreamteam
