I have only just started to get into Japanese music this week.
I have loved Japanese culture and history my whole life but for some reason it's took me until now (almost 25 years old) to really find out a lot more about it.
I started learning the language and i asked on a different website for peoples favorite artists from Japan. I'm busy filtering through about 50 that were mentioned and so far liking more than half. Some of them being:
Miyavi
MUCC
Buck-Tick
Nujabes
DJ Krush
Sex machineguns
Guniw Tools
Char
But, my music taste before the introduction of Japanese music was very varied. Favorite bands being the likes of Depeche Mode, Daft Punk, Pink Floyd, The Cure, The Prodigy, The Gorillaz, Metallica, Skinny Puppy etc etc.
I'm finding that a lot of the Japanese bands are very talented musicians. Some of the music is very well structured and atmospheric. Some of the bands i've started listening to certainly seem to go down a slighlty Industrial/Gothic route, neither of which i'm hugely fond of...but i find myself liking the way the Japanese artists do it.
1 thing i'm really not fond of is that there seems to be a lot of Emo type bands that remind of too much of western bands such as Lost Prophets...i detest that sort of music. But, i just quickly move on from those and there are a lot of good bands out there.
Looking forward to discovering more.
