Masaki, in particular from Animetal Marathon IV onward, has shown an intensely active and aggressive approach to his instrument with fluid soloing, manic slapping and popping, energetic fills, and crashing chords for punctuation.
The lyrics are almost entirely in Japanese with occasional lines of "Engrish", which may partly account for why they are virtually unknown outside Japan, except that they admittedly are playing to a very small niche market.
While they're known more for their covers, the band has a few original songs, including the ballad "Eternal Future" (永遠の未来, Towa no Mirai) from the Rurouni Kenshin film.
In 2011, Animetal USA (アニメタルUSA) was formed as a tribute to Sakamoto's band, performing English-language metal covers of popular anime and tokusatsu themes.
The band consisted of lead vocalist Michael Vescera, guitarist Chris Impellitteri, bassist Rudy Sarzo, and drummer Scott Travis.
