I nearly forgot:
Party Rockets will release their first album this year.
It will be called Triangle and be released on the 17th of decembre.
The previous single songs will be new recorded, so that it will be version of the three current members.
On 15.11.2014 they will held their first One-Man-Live at Shinjuku Blaze, including a live band. Too bad, I can't make it there.
And john_hung posted in the idolwhore thread about a sister group, named Tokyo Rockets. More Heavy Metal style. Something to look out for.
