Will there ever be another band like nirvana(Read info plz)?

The thing is.. even when there is a distinct new sound out there, people try to classify it as something else. The only way this phenomenon could happen again is if a surge of a particular "indie" band started a popular trend. Many indie artists are hard to give genre names to. So if a popular one rose, and others followed, there could be something similar to when grunge was founded.
