Calixto (Caly) Rivera has been building and repairing percussion instruments for over 40 years and is world famous for his handmade cowbells. I visited Caly's shop, JCR Percussion in the South Bronx, and with his help and generosity, I was able to put together this multimedia piece. Caly's right-hand man, Greg Askew, and the shop's "security guard," Timba the cat, are also featured in this piece and help to tell the story of what makes this place and this timbalero tick. I recorded and shot all images and audio at the shop. Michael Kamber helped tremendously with this project, along with the folks at the Bronx Documentary Center and City Lore.
