Hagane hasn't missed a step since losing tree members. Nagi the vocalist and Junna the drummer have joined and fit in fantastically. I am glad Junna has finally joined a band again since preTRiDENT aka "Girls Rock Band Kakumei'. Junna will once again Fate Gear on tour to four gigs across Canada in August. I would suggest checking out Mana Diagram as well. MD is a band formed by the former vocalist UYU and guitarist Mayto. I am not sure if they rushed to get this mini album out, but that may be why you are hearing the things you mentioned. I know Mana Diagram put out two singles before Hagane came back, so there may have been a little competition
Speed metal, They just put Junna in hyper drive and went ham. I like the song alot but not blown away by it. I would like to see them live if they ever got close to me.
