This omnibus demotape was sold during the AZALEA × DAS:VASSER × Distray coupling tour, Scene of Decadence, which began on 1999-03-09 at Shinsaibashi (心斎橋) BAHAMA and ended on 1999-04-18 at Shinsaibashi (心斎橋) NEST SALOON.
Originally, the Decadence omnibus was to be released in two types: one live-limited (this one), and one available in stores. The only difference was to be the jacket. However, the store-sold version was upgraded to a CD release (with completely different packaging), and S was added to the lineup of that version.
The UPC is the same (SMVA-002) for both the live-limited DT and store-sold CD versions of this omnibus. For purposes of the database, I've differentiated the DT was “SMVA-002(DT)”, but please note that it's technically incorrect.
