This album was re-released in 2009 and as far as I know the only difference is that the 2009 release is in the SHM-CD format. But I do not own that copy, so I would really appreciate it if anyone who has it would correct me if I’m wrong about their differences. My apologies for the lack of a write-up about the artist this time, very busy, heh. But ET-KING is hardly an obscure group, so you should have no troubles finding information about them online.
