not half filling but there was settings done like in some other concerts,especially zenith, there were some zenith which had a good hundred of empty seats if you count the number of people but it was not noticeable because of the configuration, you can see that the guy credits werra as the more popular artist though so it's surely not hate,but i guess he exaggerated the thing,just like on the other hand most of those "plein" were exaggerated because of hype
