This CD-R was freely distributed at the band's 2004-04-14 live at CASSANDRA sponsored event, Hasuike Shigoku (蓮池死獄), at Meguro (目黒) ROCKMAYKAN (鹿鳴館); and at the band's 2004-04-16 at Esaka (江坂) BOOMIN HALL. The contents are unknown―except that the cover says “2004.04 NEW MIX”, so I assume they're remixes or rerecordings of old songs.
