A few years ago, I spent a good while being evangelical about something that was excruciatingly, and probably briefly, labelled ‘folktronica’. Before a bunch of rather insipid bands like Tunng seemed to take up that banner in earnest, I wrote a lot about the solo work of Kieran Hebden, who as Four Tet had moved through an electronic reconfiguring of ecstatic, cosmic jazz and was (circa 2001) building new music out of his computer and a bunch of arcane folk records.
