The overall benefit—if you could call it that—of an early death, regardless of the nature of demise and living reputation, is the subsequent appreciation for the music. Death puts an end to your musical contribution, which can preserve your legacy. If Rivers Cuomo of Weezer died after making “Pinkerton” and the band broke up shortly after, Weezer could be revered as a truly great band with an highly esteemed musical influence, remembered for their innovative sound and creativity. But Rivers is alive and well, and Weezer has released a steady output of successful, yet comparatively less decent records than their first two. Weezer isn’t revered like Nirvana is because Nirvana didn’t have the chance to release mediocre records.
