Robert Fripp is brilliant, and is hugely present on social media. King Crimson inspired so many of the more experimental bands of the 90s, and into current day (especially harder music).

Robert Fripp also had a large hand in ambient electronic music, as well as Brian Eno, as far as ambient that reached American audiences. In regards to Talking Heads, I was born in 1979, and I can remember my dad listening to them often (along with all their videos on the brand new MTV). There are still bands with punk influences that are heavily inspired by Talking Heads.

A more modern experimental band is Melted Bodies, who incorporate punk, metal, and electronic with lyrics about current times (being popular, authoritarian control over people, insurance companies, generational trauma). They really remind me of a Talking Heads resurgence, with a grittier, more psychedelic feel (as far as psychedelia being fun and thinking differently, but also nightmarish and bad-trip territory).
