I think Missing Persons could have been really great if they would have stuck with it and maybe drifted more towards a King Crimson progressive style. I also really love Aimee Mann. She is great.
The best band? Maybe not BUT...........
Let's hear what bands or musicians you think were not necessarily the best but should have gotten much more recognition for their talent. For example: a really good drummer who was in a really crappy band and never got the attention they deserved. Or a band that had great music but the timing or managing was all wrong.
