I first came across him back in 1996. Stewart Lee, the comedian, in his other guise as a record reviewer for the Sunday Times, raved about the double album Genius + Love = Yo La Tengo, a collection of out-takes, alternative versions, covers and other assorted oddities.
Although in truth it's fairly patchy (as such records always are) it started my long love affair with Yo La Tengo, and in no time at all I was working my way through their back catalogue. One of the tracks that did catch my attention was a cover version of Daniel Johnston's Speeding Motorcycle, being performed live on a radio show (YLT had already covered it on their album Fakebook). Johnston himself phones in and provides the vocals. Like everything else Johnston did, it's very rough-edged, but also full of passion and feeling.
I gradually collected a few of Johnston's earlier records, and found a lot there in the same vein. His music's always very affecting, although sometimes that's in the sense of being disturbing. It's always worth listening to, though – it's no wonder his songs have been much covered by other artists.
