Distributed on live.
Actually this release is untitled, so i wrote frequently used title "—沈黙の代償—". You can also see this title on the back cover of release.
"五月雨か冷酷か…" lyrics on included sheet has a little difference from song on that release.
Tracks 1 & 3 are similar to tracks 1 & 5 of ～天上界の扉～ VHS.
