Jandek is one of the most interesting and mysterious acts in the history of outsider music. his musical activity spans over 30 years, during which he released over 50 albums, covering a vast amount of genres and styles, but still maintaining a very recognizable "blues" attitude. this unofficial jandek site has a long and interesting biography about "the man from corwood", which i suggest you to check out even if you're not interested in his music. (there's also a good documentary film, called jandek from corwood, which you can find on dvd on amazon i think).
"How to describe the Jandek experience? Well, first of all, it doesn't exactly fill you with 'joi de vivre'. In fact, Kurt Cobain was a fan, and I would not be surprised if Jandek was the thing that pushed him over the edge. But that's fine, really, sometimes you really do need to hear something depressing. And I like to play Ready for the House just as the light is fading on the day: as it creepily gets darker, Jandek is the perfect accompaniment for making you feel that, yep, life really isn't worth living. It's not necessarily what he says, it's the way he says it."
