As I said in my opening this question came up in another
thread , so I was not the first to ask this question .
I just gave my answer to this question in this thread .

How do you understand this ( I wrote it when I was asked to
write a concert review for a newspaper )
And sometimes I read the same in reviews of other critics .
"...BOTH THE INSTRUMENTAL PART AS WELL AS THE VOCAL PART
WERE OF A HIGH LEVEL "

At the concert I visited yesterday I asked the same question
to some other visitors , most of them agreed with me .
Not all of them .
Singer or musician , it is not a matter of level but I still
see a difference .

There is "instrumental" music and most people know what I
mean with this .
