This categorisation of recordings is of relevance primarily to the collector and completist.
There are recordings, listed here, both commercial and bootleg that have never been released in part or in whole on CD. Thus they can extremely difficult to source.
There have been many reasons put forward as to why the “Commercial” albums listed have never been authorised for CD release; it is known that Dave was unhappy with the standard of recording sound on some and asked Columbia not to do so.
Some albums not released by the major record companies have been released on bootlegs and thus not included here.
