I did not like "fusion" in general for the same reason...
"fusion" borrow from different traditions but stay on a superficial sound level often... Especially if the styles they borrow from are not near or related to one another...
For example Bollywood music borrowing from Pop and Indian classical music...
For example, listening to Nikhil Banerjee is a sacred event , listening Bollywood "fusion" is a short leisure at best at least for me...
The same is true for any other "fusion" examples...
There is very good fusion music though , lost in the general not so interesting albums mass...
For example the "fusion" of Bach with jazz by some Jazzman...Or the encounter between Ali Akbar Khan and a jazzman... They are more musical encounter event and interesting , more than the development of "a new fusion genre" as such ... the event will not be repeated on a long term creating a new language replacing the two which fusionned for an album...
Some tradition may be influenced by some other genre and integrating it slowly in history..,.It is one thing.... But creating tomorrow a style integrating two genres will not always be so interesting because it takes really genius to do so, each idioms being with his own rules...... I prefer more traditional jazz even free jazz to Pop/jazz "fusion" most of the times...There is exception for sure...
