The most underrated band in history is the Throwing Muses.
I speculate the reason they never got their proper due despite being hugely influential and innovative is their music wasnโt surface angry, it was complex, and most of the members were quite femme. This last at a time when denying and denigrating femininity among many โ and especially progressive โ women was expected. Yes, this was an understandable rebellion against unrealistic expectations but at the time any band that did not do this was seen as traitorous.
For this reason people like Amanda Marcotte and those more intellectually capable still discount Throwing Muses, despite later bands like Sleater-Kinney citing them as major influences.
The Muses forged music in the 1980s that sounded like it was from 20 years in the future. They were also one of the first major female-led indie bands, if not the first (Sleater Kinney as implied above came a good bit later).
If you want to listen to the Muses, โThe Real Ramonaโ is their best album, but all are pretty good.
Youโll probably find them derivative but the reason is because they originated a lot of the sounds and conventions that informed and shaped 30 years of later music.
