This is a screen capture of Professor Rupert Till's Soundgate App, that allows you to see and hear what it was like to be in ancient archaeological sites. This one features the Las Chimeneas Cave in Northern Spain, part of a world heritage site. It features a recording of Professor Till playing a reconstruction of a several hundred year old raindeer skin Shaman's drum in the cave, so you can hear what it sounded like in there. There's a lot of bass, you'll need to listen on headphones probably to hear it. The paintings are Magdalanian, probably about 15,000 years old.
