Field recordings of historic pipe organs played by Chase Castle in conjunction with Joseph Elliott's photography exhibition Inspired Sound: Philadelphia's Pipe Organ Heritage https://philaathenaeum.org/exhibitions/
The organs from St. Mary's, Free Church of St. John and Tindley Temple were played. The sounds of the organs and the reverberant sound of the spaces was fascinating.
Best with headphones! Ambisonic recording rendered to binaural.
