Infuriatingly brief, unreasonably fickle, annoyingly dilettante. Unchained, Vol. 6 is all of these things, and it still runs out one of the finest albums in the entire series. The heart of this collection of unused songs and fragments (lots of fragments!) is the Billy Super Duper album which occupied much of Bolan's attentions during 1975, before finally being abandoned in favor of the Futuristic Dragon album ? and from the evidence here, he was extraordinarily silly not to carry it to completion. We, on the other hand, are appallingly unfortunate. "Dynamo," "Brain Police," and "Teenage Boy Child" have all survived and sound great. And the title song, "Billy Super Duper" itself, is well-known to Bolan fans, having been released in the mid-'80s by the erstwhile proprietors of his fan club. However, amid manifold and, generally, misguided, attempts to "update" the classic Bolan sound for a new generation, fresh overdubs were commissioned for a variety of songs, "Billy Super Duper" included.
