twenty foot tall fence?

Seeking rear property line fence ideas tall enough to block view of newly constructed 7 story apartment building. There is a serious rear yard flood light problem that needs to be blocked. Currently there is a 6′ tall cinderblock wall in place, but looking for something that offers us even more privacy during the day.
I understand that legally one and two family homes in residential areas can build a fence no higher than 6′ and that no permit is necessary.
Two ideas I’m considering. Setting two 20′ poles in the ground at each corner of the lot with air craft cable run between them so that some type of vine can grow up and across eventually filling in the space or..

Planting a fast growing hedge that can reach same height. What about bamboo or some evergreen that does not take up much of a foot print? Any planting ideas?
