Initially a British folk-rock combo called Tyrannosaurus Rex, T. Rex was the primary force in glam rock, thanks to the creative direction of guitarist/vocalist Marc Bolan. Bolan created a deliberately trashy form of rock & roll that was proud of its own disposability. This 23-track disc really is an “ultimate collection,” or at least as close as it can possibly get, given the labyrinthine nature of Bolan‘s catalog. It’s not just a necessary introduction, it’s also essential for those who already have many albums, because it puts his career in perspective.
