Whenever i walk into a cd-store i always forget what i was actually coming for and end up buying something completely different...
As for suggestions:
Dir en Grey is a band that covers about all the genres you mentioned in the subject-header. Try their new mini-album
Six Ugly.
Buck Tick is actually a new wave band, but they like to crossover into some industrial. Album:
Sexy Streamliner Last year two members of Buck Tick worked on a project called
Schwein together with members of the German/English KMFDM and the British band Pig. Album
Schweinstein.
Dope Headz is the only true follow up to X-Japan, consisting of Pata, Heath and I.N.A.. Two weeks back they released their second album called
Planet of the Dope.
As for gothic, i suggest you listen to
Malice Mizer. This is the band Gackt used to be in, but their music is totally unlike what he's doing now. A good album to start with is
Merveilles
A little commercial, but good punk comes from
Sads. The band is run by Kiyoharu, formerly from KuroYume. Album:
The rose god gave me.
Thee Michelle Gun Elephant is a very energetic punkrockband led by Yusuke Chiiba.
Rodeo Tamdem Beat Specter is their latest album. Chiiba recently worked on another project called
Rosso together with former Blankey Jet City bassist Toshiyuki Terui. Their album is called
Bird.
Oh, and while you're shopping, do yourself a favor and pick up an old
Blankey Jet City album.
The above mentioned titles should be easily available. Even at HMV. I also have a list of less known punk and metalbands from Japan. If you're interested i'll post it here.
Happy shopping!!
