The problem with Marc's (solo) career is the lack of decent compilations, as he's recorded for so many different labels...the new boxset is really the first time everything (or even bits of everything) have been brought together. Singles 84-87 is a flawless catalogue of all his early solo, post-Mambas, singles. But after that, I'm not even sure there's a compilation which covers the 90s or the 00s. Treasure Box is a little more comprehensive, but even that stops in the mid-90s. I've spent years trying to piece together his output, and a lot of it is long OOP and expensive. A bit like Boy George, in some ways (but George's work is a little less pricey).
