Well, well Karl, someone else on the Bill Frisell-Gunter Grass axis!
Interestingly, I had a listen to Disfarmer on I Tunes and while I thought it was pleasant enough I eventually plumped for his most recent - 'Beautiful Dreamers', which is similar to, but I think a superb advance on 'Blues Dream' from 2001, which is one of my fave jazz/blues guitar albums. Similar eclectic mix of jazz, blues riffs and country folk but so so mellow.
Re the Grass - read and quite enjoyed 'Peeling the Onion' but noticed that his new book has really been panned as self indulgent in Germany and hasn't done that well with critics in the UK, but if you're a Grass fan, and I don't think there are too many of us these day, its a must really.
Like the photography contexts you've observed for these works. Do you work in marketing by any chance?
