Note: Also known as "B-7 Unit".
On the actual package it's named "Gay" instead of "Gai".
Next to some live videos from the band, it also features a video where the frontman, Sakevi, attacks people in the audience with a chainsaw.
Apparrantly this video was also released as a laser disc of 1000 (?) copies, that was packed like a military MRE (meals ready to eat) ration in a heavy brown plastic pouch, which you had to actually cut to get the disc out. Seen once advertised for sale when the thing first came out at around $70 and never since. Its been bootlegged onto DVD in 2007 and usually being sold on eBay.
