Yes. The song Dangerous Zone in the album Rose & Blood, the songs really crazy man. The bassline like slap & pop all the way. Maybe it sounds too funk so yoshiki reject it or sony management reject it.
Anyway, Blue Blood is one of the song that have the best solo on it. But still solo of Alive still win .. haha. IMO.
Anyway, Yoshiki & Hide planned to reform X in 2000. I dont think hide as the vocalist maybe they got someone to replace Toshi. But i think, good thing it didnt happen i wonder how would X Japan like without Toshi? Toshi is one of the most important man in X, i think without him X couldnt be successfull too. Yoshiki songs are ment for Toshi voice and vice versa. With a new vocalist, i think, X will get a bad name and their popularity will get worsen .. maybe.
Too disband a band during their popular days are good thing. That is why they are legend. Yoshiki really make a rite decision to disband a band and good thing that X never reform.
X would never be reform again, just leave it as history. But it would make fans cry if one day they have a reunion, maybe taiji can replace hide toplay the guitar. Although .. it better not because without hide .. sure like something wrong.
-----------------------------
As for what happen between Yoshiki and Taiji is actually that they has different views in how X will be. Yoshiki wanted X to be more poppish (Look at what he did to those song in Dahlia) while Taiji wanted X to be hard rock all the way and not to change their music style. So they decide that one of them had to go, since yoshiki is the leader taiji ahd to leave the band. The other reason for Taiji leave the band is that Taiji felt that his talent is wasted if he is still in X, often he wrote song for X is rejected, he got fed up and chose to go on his own way.. although he didnt do quite succesfull.
Also there's a rumour floating on the net that yoshiki and taiji get into fight and end up taiji with broken arms? that is BULLSHIT. they never get into fight, they only had mouthtalk fight, same as the rest of the member too. In what i read in Taiji book - X NO TO SHI SEI (THE LIFE & DEATH OF X), the management of X didnt allow Taiji to play for the last time on the upcoming concert but Yoshiki is the one who consult the management to allow Taiji to play for his last time.
Anyway, Taiji DID leave a big impact on X since he quit. X changed so much, ive seen X and X Japan concerts, really big difference.
