The concert would be held on the top floor of an old factory with brick walls and structural supports jutting out into the room. Around the room would be a balcony with an iron hand rail where you could overlook the whole space. At the far end of the room would be a large window divided into foot-wide squares with a spectacular panorama of a city.
The venue would double up as an art gallery with a constantly changing selection of art work on display, with some items for sale. Audience members could arrive early for the concert to look at the art work or to buy drinks at the bar/cafe. Between the structural supports would be cosy alcoves lit with ambient lighting where people could intimately talk.
The evening would start dramatically when all the lights were dimmed into near darkness while an intense spotlight marked out a lone artist. The musician would play a short piece from memory of no more than 5 mins. It could be baroque to modern as long as it was captivating. The idea would be to turn heads and draw people in to listen.
After the applause the lights would rise slightly and a presenter for the evening concert would come to the spotlight. He/she would invite people to take a seat around the artist whether a vintage armchair, beanbag or cushion. Drinks would be permitted in the performance area. Alternatively people would be free to wander around the gallery or watch from the balcony above. He/she would open up a dialogue with the artist, discussing the work they just heard and offering the audience an alternative insight. No snobbishness would be allowed and people would be encouraged to speak in normal everyday language. There would be no concert programmes but if an artist chose, they could write in chalk on the walls as well as choosing which art works they wanted to be surrounded by.
