That’s what I mean. By literal definition, he’s an artist on an “indie” label, he’s selling out the Albert Hall and getting a #1 album on a tiny, independent record label run by three blokes. (Ok, Kscope is actually getting pretty big these days, but that’s only because Steven Wilson shifts so many records for them ).
But the accepted definition of “indie” has come to mean a certain musical sound.
And that’s not so different from “prog”, which has by popular definition come to mean a certain musical sound, but actually doesn’t mean that at all.
