This set is said to combine all of the surviving BBC recordings with previously unreleased sessions taken from BBC Transcription Discs, off air recordings made on reel-to-reel tape recorders and the occasional cassette tape. The box contains 16 previously unreleased Tyrannosaurus Rex tracks, and over 20 T.Rex tracks never before issued. There are also a dozen interviews many of which have never been commercially available. The 117 track box set kicks off with some June 1968 John’s Children recordings and the curtain closes at the end of disc six with a couple of T.Rex tracks broadcast on the David Hamilton show, less than a month before Bolan’s untimely death.
