Cava xi.xi.86 was a concept album split into two parts, side 1 formerly called gravi tracks 1-4 and side 2 le ghiaie tracks 5-7.
Mixed at the stanza delle uova (1987) using a (4+4) multi-track system.
Two more compositions have been added to this reissue:
Track 8 (cube version of gravi) and track 9 (with a little help from l’orchestra dei becchi di Fuji), both of them using ’86/’87 archive sessions, re-worked and digitally mixed at my ground floor studio (2019).
Re-mastered from the original tapes.

All material recorded from November 1986 to April 1987 at the laboratory and its surroundings.
