Wow, this shit just came up on shuffle and it's been years since listened to Babylon! Leopardess Marry came on and seriously that song came out almost 10 years ago. Has it really been that long? Still so catchy! Shoot, I'm also curious what happened to Takuma, he was a pretty decent singer for a VK guy so I'm surprised if he didn't get picked up immediately after Babylon breakup.
Only the first half of CLAN GENE has Misa songs, the second half is mostly Youki songs which don't sound Misa-like at all (except for Sola and Tsuya, because of Misa's programmings). My suggestion is trying the 2005 CD's, I think those are the easiest to get into the band for a Misa fan.
CD Japan has a good selection of CD's, I'd reccommend Soukouya and the No no sick kamikaze single. For other out of print CD's, try Closet Child, they've got some of their old CD's for cheap, and they accept overseas orders: http://closetchild.jp/html/newpage.html?code=7
I hope to see him sooner or later with a new project. I really enjoyed all this 5 years he was in babylon. and the best of luck for the newborn babylon... will be tough to continue without the leader, but I hope they can make it, I'll be supporting them.
