That Guardian bio is shit, it blathers on for paragraphs about his work with Madonna and then barely even mentions by far his most important work, his rework of Barber's Adagio For Strings with Ferry Corsten - that piece transformed an entire genre and played a huge part in taking trance from hippie festivals to sold out arenas.
I don’t disagree and the Guardian should have done better than make most of the article about Madonna. However, unlike Russ, the vast majority of the population were not dropping tabs and clubbing in the 1990’s, even if said arenas were sold out. Whereas most people have heard of Madonna, whose career he helped relaunch and for which he won Grammies. So it’s arguably his most widely known contribution even if it’s not necessary his most important.
