@Keep_on_Kraken Frank is a great example of how hard it is to make such a judgement. Who would have expected there are up to 3 active bands of former bandmates playing his music today nearly 30 years after his death? No, they’re not wildly popular, but people go and they know all the songs by heart. I can attest to that coz I’ve seen both Dweezil and The Zappa Band in the last couple years. The present day composer refuses to die!
