Rooftop is always a good place for listening. Climb up high for a beautiful view from the top of the mountain. Take an aural rest, have a humble cigarette break without any CCTV there.
I put an amplifier is put at the bottom part of the ladder at the rooftop.
A piezo microphone is installed at somewhere else on top of the ladder.
It is an invitation from me to get your there and listen.
Climb up the ladder and open the ears again, though it seems to be a little bit tired and dangerous.
The view there is good. The sound there is also good.
