Rummaging in workshop

In one of the buildings adjacent to the building yard, there is a storage room/workshop that can only be accessed from the street. No one uses it, but it seems that the space is rented out. That day, I unexpectedly heard someone moving around in that storage room. On the side facing the yard, there’s an opening as if a single brick were missing. I placed a recorder nearby and recorded the sounds of that person moving around in the workshop and shifting various objects, as if they were searching for something in the cluttered room (Roland r-07)
