- Q:Other than the 'cores, rap metal and nu-metal.It's a tie between goregrind and brutal death metal for me.BQ: Worst metal song you've heard?
- I think so but it wont be in stores for quite a while.
- Q:i made my parakeet some toys with plastic beads and stars, and put some bells and colorful metal rings on them...is the metal bad???
- Well, iron is a metal that doesn't contain carbon. Both are elements i.e. substances that can't be broken down into simpler substances by a chemical reaction. Most of the known elements in the universe are metals eg. aluminium, gold, copper, but the non-metals are more abundant eg. oxygen, hydogen. They are termed metals because of their structure and the way in which they bond to other elements. Maybe by metal you meant metal alloy. Steel is an alloy (mixture) of iron and carbon. I think all alloys of iron have some carbon in them. Don't know if this is what you meant but it was good trying to think about an answer.
- Q:Eg: hardcore, death metal, heavy metal, screamo.... Etc
- Groove metal is a subgenre of metal which is slower and relies more on groovy rhythms rather than on fast thrash riffs. In many cases groove metal features downtuned guitars (in man cases also dropped tunings) and it is usually in mid-tempo. Also, groove metal usually features harsher vocals than in thrash metal and overall the sound is heavier. Groove metal examples: Pantera, Sepultura (later), Machine Head, Exhorder etc. BQ: Thrash metal BQ2: Death metal BQ3: Alt metal BQ4: none
- Q:what is the most expensive metal in the world ????
- aerodyne flex between the buried and me blotted science born of osiris brain drill burning the masses cephalic carnage circles cloudkicker the contortionist cyclamen david maxim micic entrosolet ever forthright friend for a foe haunted shores intervals jeff loomis last chance to reason meshuggah monuments nemertines the nocturnal chaos painted in exile periphery protest the hero red seas fire skyharbor substructure tesseract 24192
- Q:some Nu Metal bands are:KoЯnLinkin Park (their older stuff)Limp BizkitDisturbed (their first album)SlipknotStatic-XP.O.D.Papa Roach (their older stuff)
- Just as much as they ever have. I know quite a few that do but I listen to Metal so I'm naturally going to know a lot of others that also listen to Metal. It also depends on what you consider Metal. Metal is a HUGE category!
- Q:I thought they're the same, tbh. But someone told me not.If there's a difference between them, what is it the difference?And give recommendation of black metal.. Is the band Skeletonwitch black metal?
- Metal is a sub-genre of rock to begin with Power Metal Alternative Metal Industrial Metal Heavy Metal Speed Metal Thrash Metal Metalcore Deathcore Death Metal Black Metal (though a few Death bands do surpass Black bands such as Deicide)
- Q:Now days there so many up and coming bands that aren't even metal and yet they are called metal.I'm sorry but metal is Dimmu Borgir,Satrycon,Decide,Gorgoroth,Impaled Nazarene,Behemoth not all Green day and Bullet fro my valentine.
- Depends on the metal. Aqua regia will dissolve gold/silver etc. It;s a 3:1 mix of concentrated HCl and concentrated nitric acid... But that's not going to be much help if you are just after something lying around in the house rather than in a lab... Can't really help you with household items really, sorry!
- Q:What are your views on Death Metal, Melodic Death Metal, Extreme Metal, Power Metal, Metalcore *My favorite*, Progressive Metal, Rapcore, Speed Metal, Thrash Metal, Heavy Metal, Doom Metal, and Black Metal... and any others I missed, do you see Metal as evil, or do you see it as a genre of music... and I mean all of the past history and bands of Metal...
- That guy up there isn't even giving you actual Metal, here's some bands from a pure Metalhead: Children Of Bodom Amon Amarth Ensiferum Eluveitie Death Angel Witch Megadeth Rammstein Cradle Of Filth Burzum Mayhem Motorhead Turisas Sabaton Black Sabbath Judas Priest. Motley Crue Skid Row Accept. All of these are Metal. The first ones are mainly Melodeath and death metal, a few of folk metal bands in there, and a couple of glam metal and well as classic metal, industrial, black, pagan, speed, thrash in there too.
- Q:i always thought they were heavy metal
- no one actually listens to screamo, because if they enjoy what you call screamo, then they just consider it metal.
- Q:any good metal,heavy metal,screamo bands you know
- JDiamond- that link hasnt got anything about metalcore
