Yes, Sean, if we extract the words along with its support of Quercus then there is little to disagree with in that sentence. Mind you, only 2 of his first 10 albums (1967 - 1971) were on ECM but since 1976 he has recorded exclusively for ECM and that has been dozens and dozens of albums.
My objection was to the stated influence of Querecus; I'm afraid that I phrased it rather badly.
