Reddit mentions of でんぱーりーナイト(カセットテープ 完全限定生産盤)

When it was announced I put in a request with CDJapan and they stocked a few copies (three, to be precise) which I grabbed one from, and the others sold out fast. As of yet I think only Amazon.co.jp still carries it, but it's far from as accessible as CDJapan (which is set up in English and has clear info on international shipping + accepts PayPal), and the price they're offering it at is pretty steep at ￥2,900 (whereas I paid $10 tops at CDJapan).

Regardless, Dempagumi.inc is highly worth looking into otherwise because their music is absolutely insane and insanely great. I cannot recommend tracks like ノットボッチ...夏, Den Den Passion, Chururi Chururira, Future Diver and W.W.D. II enough. Their first full album (World Wide Dempa) is really brilliant too.
