I actually have the Blu-ray version of this, which I have yet to watch because I don't have a Blu-ray player. Unlike the Blu-ray version, this DVD was released through specialized distribution channels, so I could not buy it. Well, there's always a way around it, but I missed out on spending excessive amount of money that time.
While I was in Japan again last week, I picked this up for Y2,980. Of course, it's a used copy. DVD version doesn't have the audio commentary, but hey, at least I got to watch it.
It's 190 minutes of mostly interesting stuff. It's a great buy for Suara, Koyama Tsuyoshi, and Utawarerumono Radio fans. To Heart 2 radio fans might not get as much out of it, though.
Audio is recorded using far away microphones, so signal-to-noise ratio isn't so good, but the resulting audio isn't messed around with, so I don't have a problem with it.
