Nirvana

They started in Washington. They had their first album name bleach. They did not sell many copies at first. They signed with sub pop record company. And released the album nevermind. It hit number 1 on the charts fairly quickly. A couple songs in that album that were incredible were it Smells like teen spirit and Come as you are. They are grunge music and they brought it to popularity in the mid 90's. In 1994 Kurt Cobain killed himself which broke the band. Kurt Cobain was their lead singer and guitarist. Nirvana didn't last that long but as they did last they were great.
Pros: Brought grunge music into popularity and were just a flat out good band
Cons: Didn't last long due to drugs
Overall 8.5/10

Shinedown

Shinedown is an interesting band. They have not really started to shine and come up until 2011. Two of their biggest hits are incredible songs which are Diamond eyes and sound of madness. These are both very good songs and show how much potential they have. The problem with Shinedown is after i heard these two songs i decided to go listen to the rest of their songs. They were very mediocre and seemed gloomy. One thing i thought about is they would be an absolutely outstanding band if their content was like those two songs that were huge hits. In those songs they have a great projection of vocals and their guitar parts are outstanding. The problem is they have a large lack of effort in the rest of their album.
Pros: Good hits and a good singer
Cons: Lack of effort in most of their music and the songs do sound generic.
Overall 5.5/10

Tenacious D

Tenacious D is a rock band that is mainly comical. Although Tenacious D sings with a comical approach a lot of their music is musically genius. The lyrics are hysterical the riffs are rocking and the music is original. A lot of their songs came from their movie Tenacious D and the Pick of Destiny. A few popular songs that came from that were Master Exploder, Beezleboss and Kickapoo. Tenacious D has three very popular songs that most everyone knows about which are Master Exploder, Tribute, and F*** her Gently. Also with the Tenacious D they put on a good show.

Pros: Funny, great lyrics, original and rocking music.

Cons: Most rockers/Metalheads don't look for comedy when trying to find music.

Overall 8/10

Rammstein

Rammstein is a great german band yet not so good at times. They have a very good heavy metal sound with very deep and intimidating vocals. Rammstein has a few popular songs in America. Most songs that Americans know about Rammstein are Du Hast, Sonne, and Amerika. Those are three great songs that are very popular. When you ask anyone what songs they know about Rammstein those are the three answers you get. One of the reasons to that is because Rammstein is one of those bands where a lot of their music sounds the same and only a few songs are great and the rest fall in the decent category. I really enjoy most of their songs but i do have to admit a lot their songs sound just alike. Overall Rammstein has a great metal sound and a select few songs should be categorized as amazing.
Pros: Many songs of theirs are absolutely amazing. The vocals are very deep and sound great.
Cons: A few incredible songs a few good songs but a lot of decents which is not a good thing. Also many songs sound alike.
Overall: 7/10

Scars On Broadway

Scars on Broadway is a great Metal band. They are led by Daron Malakian and John Dolmayan. Daron Malakian is their Guitarist and vocalist and his vocals are really strange and great. His vocals have improved from his System of Down days and his guitar riffs have not. His guitar riffs are still pretty good but his riffs from System Of A Down were a lot better. They have a few great songs that i really enjoy which are They say, Chemicals and World Long Gone. Those are three great songs that have a great metal sound to them.
Pros: Good vocals and very interesting metal sound, funny lyrics
Cons: Sometimes their songs don't sound very crisp/clean, Guitar riffs are pretty good but simple and not as good as they could be.
Overall 7/10

Slipknot

Slipknot is a pretty good metal band. They are a band that put together a lot of hard metal styles to create pretty good music. One thing i really like about Slipknot is there quantity of music. They have released a lot of songs. Another thing that is great is how they aren't afraid to try new things with their music. Like making the song Iowa which was 15 minutes long and was unlike all of their other songs. They make some good music and they are a classic metal band.

Pros: Fearless music making, good quality and mostly quantity with songs.

Cons: Some of those new things people do not like. I disliked Iowa just for that but it still shows they want to take shots.

Overall 6.5/10

Red Hot Chili Peppers

Rhcp is a good band. They have a lot of styles of music. They aren't metal and only a little is Rock but they are a funky band. They have a lot of different styles some songs like Can't stop is just a funky rock. Snow hey oh is just rock. Under the bridge is a very soft rock. And some songs like If you have to ask are really funky. The problem with all the variation is some people are only interested in one type of music. A lot of people i know like the Rock side of Rhcp and dislike the funky because that is not for them. Overall all the members of the band make the band who it is. The bass is funky the guitar is sick and the singers voice is easily distinguishable.

Pros: Great styles of music and good combinations like Funky rock.

Cons: So much variation that some people won't be interested in some of the music
