Introduced by Southbank Centre’s artistic director, Jude Kelly, this latest instalment of The Rest is Noise festival felt like one of those events that rarely finds its way into the concert diary. A packed hall witnessed one of those feats of sheer physical, intellectual and emotional energy that you are unlikely to forget. With the 76-year-old Philip Glass leading his ensemble on keyboard, his three-and-a-half-hour piece Music in Twelve Parts passed in a flash of obsessive brilliance.
Not that this type of minimalist concert would always have filled a large concert hall in the past. In the early 1970s, this work – and those by Steve Reich – were given a very wide birth by audiences and the musical establishment alike. Despite its clear links to popular music, the repetitive, accumulative nature of Music in Twelve Parts would have infuriated most listeners and only a small cult following was established. For the musical elite at the height of the avant-garde, when the “barriers” of rhythm, melody and harmony were being challenged and broken down, the detailed analysis of all these elements by Glass et al was seen as a conservative and retrogressive step. It wasn’t to be until much later that their contribution to the musical landscape of the 20th century was taken seriously at all. But after 40 years when composers have been trying to find new ways to reconnect to audiences after the free-for-all of experimentation, it is possible to see Music in Twelve Parts by Philip Glass for what it is: a superhuman achievement of complexity and subtlety on a level with any work by arch avant-gardist Pierre Boulez.
And this is a work that certainly cries out to be heard live. The tension created by the performance itself, with players stretched to the very limits of stamina and concentration, is palpable in the hall. Despite its long stretches of dance-like rhythmic patterns, this is not background music, but it demands to be heard and appreciated for the intricacies of its musical arguments. What was special about this performance by the seven musicians was a sense that this performance linked to the original performances in 1974, with three of the performers having been part of that original group, including the composer himself. After 40 years, the performance felt as vigorous and perky as any of the recorded versions.
