A few weeks ago, I asked in my column; where have all the protest songs gone? It seemed few musicians were commenting, with melodic accompaniment, on the state of the world.
The answer seemed to be that commercial interests had neutered music of political content. In the last few days, the media has questioned the value of music on politics via articles about Bruce Springsteen backing the Obama campaign with appearances and a song of support.
Certainly there is evidence of a reverse of this power equation. In northern Mali, rebel militia have declared a ban on music, saying it undermines strict religious adherence. They clearly fear the power of music. For Mali, this is the economic and social equivalent of cutting off their main export industry.
Toumani Diabate, the Malian kora player, known in the West for his work with Ry Cooder, Damon Alban and Bjork, describes culture as the "petrol and mineral wealth" of Mali.
Its music has won international acclaim, awards and recognition. Carried by musicians such as Tinariwen, Toumani Diabate, Rokia Traore and Ali Farka Toure, Mali's glorious sounds have become a major export. Now musicians are fleeing, pursued by threats of having their fingers cut off. Many have joined the 500,000 refugees now living in camps in Algeria. The threats of death appear to be aimed at killing off any musical resistance. To have such a fear of music must mean it has a power that requires control.
