Although 'Bad' was deservedly a huge success, Michael Jackson and some of his fans were disappointed with the result. It had not sold nearly as well as Thriller for a start and there was certainly nothing like 'Billie Jean' on it. So, for his next album 'Dangerous', Michael opted for a change in direction, replacing legendary producer Quincy Jones with more contemporary Teddy Riley. The result is a far more dynamic and forward-thinking album than 'Bad' was, as some of the tracks - 'Jam' and 'Black or White' for instance, still sound up-to-date today. All of the music on this album is solid and some of it, like 'Jam', is certainly pure funk...except perhaps 'Will You Be There' and 'Heal the World', which are a little self-indulgent and become a bit of a dirge after a few listens.
As it turned out, this album was amazingly just as commercialy successful (worldwide) as 'Bad' was, selling a similar number of copies. It does flow better overall and has a longer running time as well. There is also more solid single material on this album than on 'Bad'. Bear all that in mind and you should purchase 'Dangerous'...as well as being one of the most popular albums of all time, most of its material is simply great music.
