Riyu’s Summer Vacation

Hi guys. I noticed that someone uploaded the whole of this concert onto Youtube, and promptly keepvid’ed the whole thing. I’ve been listening to it almost non stop this last week, and I’ve been trying unsuccessfully to find somewhere online to buy the DVD – it’s just too good :O
Could any of you help as to where I can buy it? I tried going through the official i-revo site, but my access was denied for some weird (and irritating) reason. Amazon Japan has nothing, and Amazon US even less. Thanks!!
