Yes, I know King Crimson and it's no wonder they were underrated (if with "underrated" you mean commercial success). Their progressive music was way off mainstream. Like all influential bands or artists, King Crimson were never underrated in critics' books, by the way.

There were and are thousands of bands and artists which are commercially not so successful, but each of them has their fanbase.

Japan came to my mind when I read the OP. I never really liked the band's music (too exalted), but when they split, each of the band's members created great music solo and in collaboration with each other and other musicians, especially David Sylvian (who worked with King Crimson's Robert Fripp on several occasions).

King Crimson is amazing.

Robert Fripp is a g-d. He played some of the greatest guitar solos in history, like "Baby's on Fire" for Brian Eno or anything off of "Heroes" by David Bowie, and his Guitar Craft schools are heavenly and he can turn any tone-deaf kid who can't tune a guitar into a supergenius guitar monster.

Anytime anybody asks me who the most underrated band is, the answer is always the Residents, because nobody even knows who they are. I've been a huge fan for years, and I still don't know who they are. They've never revealed their identities, and they've been making music for about 38 years.

Here are 4 short music videos (1 minute each) by the Residents:

There's about a trillion no name bands you could mention.

The Jonas Brothers.

Nightwish.

They are big considering. but still they should be a lot more for their talent
