"Miyavi announced in a video comment (link posted on his official website) that he would like to 'try screaming in the background again' and thus found an amazing guy (older than him) and will start their band in 2007. Although he cannot say more, he also assured that he would also like to continue producing as a solo artist."
Found this on a site
This was before it was known that Miyavi was a part of the band. so he will probably not the lead singer. start listening to his music lately. he sounds good
