The Unreleased Beatles" details the incredible wealth of music that the Beatles recorded but did not release. A staggering amount of material is examined, from unreleased studio outtakes, live concert performances, home demo recordings, fan club Christmas recordings, and other informal demos done outside of EMI studios. The book includes chronological entries for all of the Beatles's unreleased recordings of note from 1957-1970, including special information on BBC radio recordings from 1962-1965. There's also details on unreleased video footage of note from 1961-1970 and outtakes from 1990s interviews filmed for "Anthology." An entire section is dedicated to covering Beatles bootlegs, Beatles songs recorded by other artists in the 1960s, and never-recorded material. Lastly, the book includes rare stills from film footage of the group that hasn't been made commercially available.
