Session members
Due to the illness of Nico in 2007/2008 Rock4 had to replace him for a number of concerts. They found two excellent singers to take on this job. Their names are Rob Didden and Just Kalverkamp. During one of their miniconcert tours in Austria/Germany, we interviewed Just about his temporary Rock4 career.

Hoe ben je als vervanger voor Nico bij Rock4 terecht gekomen?

I had already met Jeanine at an acapella festival (Vocal Group > Festival at Tilburg). I had met Luc Nelissen before during a percussion workshop with Wes Carol. When Rock4 was looking for someone to fill in for Nico, Jeanine contacted me (after a thourough search of the Internet in order to find me).

Are you member of another acapella group

Vocal Group On Air. Een 5-stemmige acapella groep with 2 ladies and 3 men.

What was your first impression of Rock4

A relaxing group of people with a healthy attitude. The fun they have all keeps it light and airy.

Was it difficult to study for the shows?

De Queen show was OK, but Timeless is much more difficult. It is often difficult to tell the arrangements apart, because they consist of various, often not cohesive parts..

Which is your favorite Rock4 song?

Hallelujah. A great song to sing.

Which is your least favorite Rock4 song

The Prophet's Song

What kind of acapella do you like

I prefer jazz/close harmony, the more "classical" acapella

Which song would like to try sing acapella?

To many to mention, but a few examples:

Strike up the band - G. Gershwin (arr Quincy Jones)

Ne me quitte pas / les Marquises - Jacques Brel

Thriller - Michael Jackson

Luc D: horny teenager

Peter: older youth

Luc N: frau Nelissen

Nico: health health
