Their conception was very well-timed in regards to musical trend; they were on an upward climb in terms of their successive albums; they fused elements of post-rock and drone to make very uplifting electronic music. They were so relevant a few years ago and then just vanished.
I noticed they're on the primavera sound lineup so perhaps they producing new content, however their goofy website (http://www.fuckbuttons.co.uk/) doesn't really point to that.

Did anyone catch them live? Were they good? Does anyone recommend any bands akin to them?

listening to flight of the feathered serpent...still sounds juicy as ever
