I only heard about the following item about 2 months ago. Until then I did not even know it existed. Today I got a package which contained this release called バトルカプセルから愛を込めて <ALLEX RECORDS通販予約特典CDR> by 宇宙戦隊NOIZ, released in 2004. It contains an hour of discussions by the band, probably about this single and more.
