60 – 40 – 25: a series of numbers that have inspired an exceptional concert. They refer to the 60th anniversary of CERN, the 40th anniversary of the CERN Choir and the 25th anniversary of its direction by Gonzalo Martinez. On the occasion of this collision of anniversaries, the Committee of this CERN club decided to organise an appropriately significant event to celebrate the important worldwide role that CERN has played for 60 years, the fact that the CERN Choir has brought together amateur singers for 40 years, and finally the decisive role in the Choir’s history of its director, Gonzalo Martinez.
