Bronze Artwork Large Played With Kettledrumsticks Musical

I´ve found a more than 2 meters high and wide bronze artwork hanging upright. It has several blocks on its surface, looking just like a upright hanging town. On 5 of the "houses" i played a rhythm, using rather hard drumsticks für kettledrums. Recorded with zoom h4n with 2 schoeps ccm4 mics.
