And on the vegetable orchestra website I found that eating is, indeed, part of the concert experience:
A concert of the Vegetable Orchestra appeals to all the senses. As an encore at the end of the concert and the video performance, the audience is offered fresh vegetable soup.
But I have to mention that hundreds of millions of people (actually more than three times the population of the USA) around the world are going to bed hungry, even starving. Such orchestras can only exist where there is plenty of food.
