|Rahxephon-Volume 7: Crescendo||=|
The Region 1 version of this disc was released at the end of 2003. As far as I can tell, the two versions have the same features, the same episodes, the same extras (except for the choice of trailers in the previews), and even the same cover artwork. The R1 transfer sounds like it is at least as good as this one.
Once again, you can probably be happy with either the R1 or the R4. I am happy to have the Region 4 in my collection.
