But then again, we're talking Dylan here. Is it possible for the guy to make a bad album?
Bahahaha. Zero, you need to take a trawl through the 1980s.
Hahah seeeerious. I've only met one person in my life who
arguably was a bigger Dylan fan than I consider myself to be (and that's kind of saying something, because I took an auditorium-size appreciation class on him), but I will be the first one to admit that he has made some absolutely fucking horrendous music. Awful.
In response to the general topic, I often feel that an artist getting married and entering what music writers call "domestic bliss" is when their tunes really start to go downhill, not their divorce. Most artists I really dig and pay attention to seem to have a mid-20s, drug-addled, romantically-turbulent, philosophically-excating faith crisis period which tends to produce what is referred to as the "golden age" of their creativity. Then, like Dylan, like Lennon, like Costello, like Oberst*, like Adams, they all turn 30-35, and if they don't necessarily get married and have kids, they at the very least find something they latch onto and become comfortable and complacent. And I'm happy for them as people, because no one can be an artistic martyr their whole life. But the quality of their music almost invariably suffers.
*He started early. Conor's 26 is everyone else's 33.
