I am looking for some recommendations of good Japanese pop or rock bands. Preferably with a male lead singer.
Hizaki Grace Project was a short lived, but amazing band. Great vocalist and, of course, Hizaki on guitar.
J/Rock: TK from ling tosite sigure (see if you can find "Abnormalize" from Psycho Pass, "Signal" from 91 days," or "Unravel" from Tokyo Ghoul)....good stuff. J/Rock: SID ("Monochrome Kiss" and "Enamel" are pretty famous.) Solo artist for J/Pop: Mamoru Miyano (has good vocal range...well he is a voice actor as well!) I love J/Rock or J/Pop. The best way to find artists is through anime, IMHO. I'll post again if I think of anymore bands/singers. http://emptyclosets.com/forum/entertainment-media/232485-anyone-here-like-jrock-jpop.html Here is a link to a thread I started awhile back...may have some more suggestions.
Matenrou Opera - Orb Siam Shade (one of my favorite bands ever, amazing guitar player) - Calling, or their big hit "1/3 no Junjo na Kanjo"
