The Colón Ring is an abridged seven-hour version of Wagner’s epic Ring, premiered at Teatro Colón in Buenos Aires in November last year. The performance is available on DVD and Blu-ray on June 3 in the UK – coinciding with the composer’s official bicentenary – along with a documentary, ‘The Colón Ring – Wagner in Buenos Aires’, capturing backstage drama that constitutes a saga in its own right. The  Colón Ring might seem an impossible feat to stage Wagner’s Ring in one evening.  ‘It’s not a weak piece, the Ring,’ the director Valentina Carrasco  says toward the beginning of the documentary. ‘It will survive all of this.’
