Up to Appetite for Destruction, they had a good edge, raw from the sewer. Then their egos got way too big. The double album(s) were patchy - brilliant in spots and dodgy in others.
But the idea of spending months, even years in a studio to record a f&%king rock album is beyond me. Black Sabbath did their first album in 3 hours. Other good bands can do it in a couple of weeks. Even Pink Floyd with all their sonic experimentation never took more than a couple of months. But if it takes you a month to do one simple guitar-bass-drums-vocals song, it's time to change careers, because you are relying too much on the production and not enough on talent. And after, what, 14 years since the last proper album, I ain't holding my breath.
