Forty years ago Bob Moog invented the first synthesizer. It defined electronic music in the 1960s. Now Moog is back with what he calls the greatest synthesizer ever made. It’s his first instrument in decades. Only one problem: “British trademark law means that the 70-year-old creative genius cannot sell his synth under the internationally recognised brands of Moog Music or Minimoog, because they have been appropriated by an entrepreneur in Wales.”
