All was actually the last Descendents lineup with a succession of different singers! Descendents had some...interesting bass playing in parts but it's actually one of my least favorite things about that band. Good band though!
Here's a left-field one: Beefeater (Washington, DC), who played a pretty weird mix of funk (including slap bass!), punk, and metal. Some of the guitar playing reminds me of Bad Brains.
Oh, and the Big Boys (Texas) who were a more straightforward punk-funk band.
And hell, New Model Army (UK) were a pretty intense post-punk band very much built on a distinctive bass tone and style. Which is weird because I guess they went through a few bass players, but somehow they all sounded exactly alike. Band-bass-rig-syndrome, I guess.
You know your history my friend. Beefeater! Awesome.
