Mucc is a pretty good japanese band. They do sort of (slow rock - medium rock - hard rock - gothic rock - metal songs) which are so unique that they have their own genre of songs. Their latest album is "Kuchiki no tou", a must hear album. If you have some time on your hands and got bored of listening to the same s**t again, try this band. Their songs cant be categorized as any genre because they could suddenly change an extreme song into really slow song and vice versa.
Anyways, I would recommend the following songs if you would like to listen:
- 1) MUCC - Dare mo inai ie (sort of Gothic/hard rock)
2) MUCC - Gentou Sanka (NU-Metal)
MUCC - Ranchuu (Hard rock)
4) MUCC - Bouzenjishitsu (mostly hard rock else medium)
5) MUCC - Hikan Shugisha ga Warau (Alternate metal)
6) MUCC - Dakukuu (Hard rock [Coal Chamber type])
7) MUCC - Isho (Post Grunge)
8) MUCC - Rojiura Boku To Kimi e (Instrumental metal + Medium rock)
9) MUCC - Akatsuki Yami (Slow rock + Medium instrumental rock)
10)MUCC - ZutaZuta (Loud rock)
11)MUCC - Namonamuki Yume (Punk rock)
12)MUCC - Ware Arubeki Basho (Weird rock + Instrumental NU-metal)
13)MUCC - Yakeato (Medium Gothic rock)
14)MUCC - Oboreru Sakana (Slow for 3 minutes, Hard for 2 minutes)
Anyways, if you need a sample 30 second of any song, I will glady post it.... because methinks we are not allowed to post complete mp3's for some legal blabble, are we
Edit: I linked them to Radioblogclub search results so you just have to click on the song to listen to them.
