Among the band’s extensive back catalogue, one record sits alone – composed in accordance with the group’s infamous Theory Of Obscurity, Not Available, and the saga that surrounded its release, comprises perhaps the most truly ‘Residential’ work the group have yet produced, and remains their most intriguing album among fans and critics alike. Now, over forty years after that saga unfolded, and produced using the original masters and multitrack tapes, this package explores and expands the classic album in unprecedented detail.

2CD - Disc 2 reveals the original 1974 X Is For Xtra (A Conclusion) recordings which were adapted, edited, remixed and reprocessed into Not Available by Ralph Records in 1978. Familiar and recognisable in places, entirely unheard in others, this revelatory new material sheds paradigm-shifting light on a masterpiece of 20th Century pop culture.
