Harry Bertoia was a designer, artist, and sound sculptor who worked mainly in metal, using large bundles of metal rods and tines that play unison pitches. His sound sculptures produce unique ambient sounds. He released multiple albums called Sonambient on vinyl throughout the 1970s-1980s. His work is continued by his son Val Bertoia who continues to make new sound sculptures inspired by the philosophy of sound art started by his father. A collection of his instruments are held at his bard workshop in Bally, Pennsylvania.

here is a video of Val performing on some of the instruments in the collection.
