- Q:Which one is better?I'll go on a limb and say Psychedelic rock.
- Heavy Metal Machine. The live 2008 version of Heavy Metal Machine is my favourite version of the song, but I love the album version too
- Q:what kind of metal is pewter?
- Their early material is nu metal. Then they went alternative metal after nu metal's popularity died out. Now they seem to be a mixture of alt metal and modern heavy metal. I think their most recent album is the most metallic stuff they've done so far. Although they're still not anywhere the near the heaviest band in the world as they claim to be lol. They're often classed as nu metal but I don't think they are anymore. Most bands that were originaly nu metal have changed their style since the mainstream snapped out of their nu metal phase. And they aren't death metal in the slightest. Death metal is bands like Nile, Morbid Angel, etc.
- Q:Also, do divalent metals form ionic or covalent bonds?
- metal>shiny surface, malleable, good electricity conductor, good heat conductor eg: Cu, Zn, Pb, Fe, etc. etc. nonmetal> basically opposite of metal?xD
- Q:I mean, are any of their musical qualities power metal-ish? esp the song blut im auge
- non metals or metals that have reacted with oxygen (O2) eg oxidation of iron making iron oxide (rust) magnesium burning in air to give magnesium oxide (MgO2)
- Q:They don't sound like heavy metal to me..
- for Hardcore i would say Wall of Jericho there a cool band to see live and there singer Candace is a super nice person also if you like Black Metal you should check out Thorr's Hammer there singer Runhild has an amazing voice now she is in the band Khlyst but my favorite was back in the day with Thorr's Hammer
- Q:Which genre do you prefer?BQ1 - Favorite death metal band? Narrow it down to 3-4 bands if you have to.BQ2 - Favorite thrash metal band? Narrow it down if you need to..BQ 3 - Favorite Death metal album and vocalist?BQ 4 - Favorite thrash metal album/vocalist?
- There are a number of metals used for communications. They tend to be used in different places depending on the application. I would guess that the most commonly used metal is copper for wiring, but you'll also find lead and tin used for solder, gold for contacts and connectors. Once you get inside the actual electronics, you'll find semiconductors like germanium, gallium and arsenic as well as conductors including copper and aluminium. The source below also has tables for resistance for various metals in wire form.
- Q:Just oldish stuff is metal right...?Well I like it but..there are new metal bands out there and just becuase they'r not form the 80's that doesn't mean they're NOT metal.Because to me metal is type of rock that is heavier..
- Venom is often considered the best death metal band ever. They were hugely influential on everybody from Megadeth to Carcass. Others include Celtic Frost, Bathory, Sodom, Morbid Angel, and Sepultura.
