The Andrea Amati 'King' cello, thought to be the oldest cello in existence, is performed by Joel Koestenbaum at the National Music Museum, University of South Dakota in 2005.

The Strad's May issue, out now, examines the clues the 'King' offers to the evolution of Amati's designs and working methods. Our June issue will report on a project to recreate the instrument to its original dimensions.
