Some genres are so overcrowded with crap that some people just write them off as bad genres. In mainstream music it happens with Hip Hop, people hear Lil Wayne's newest track on the radio and immediately denounce all Rap as garbage. They never think that if they just look past what they hear on the Radio they could find that talented Rappers Do actually exist. The same thing happens in alternative music. People see terrible bands like Attack Attack, I Set My Friends On Fire, Bring Me The Horizon, Drop Dead Gorgeous (I could go on for days but i'll stop there) reach a certain level of popularity and they just write off all emocore/metalcore. However, just like the Radio, if you're willing to look past the giant wall of crap that is those bands you'll find that there are quite a number of bands doing amazing things with Screamo and Metalcore. Take Inhale Exhale, a metalcore band who's living proof that when done right, metalcore can be just as creative, intricate, dynamic, and intense as any other genre. The band makes use of the clean/unclean vocal setup that characterizes most bands of the genre, and for the most part they follow the same format of heavy/melodic/heavy with the unclean vocals accompanying the heavy parts and the clean vocals accompanying the melody. So what makes them different than every other band? Well, bands like ISMFOF and Attack Attack (And The Devil Wears Prada...I HATE Them) don't really put any effort into making their music. Let's put it this way, my friend picked up his first guitar a few months ago, he didn't have any talent for it, but he was determined to practice and get better, after about a week he was able to play every Attack Attack song. Shortly after that he stopped listening them entirely. So basically, these bands songs are so simple that anyone with a basic understanding of how to play guitar can pick them up quite easily. Inhale Exhales songs, on the other hand, are complex, intricate, dynamic, and intense. The heavy parts are some of the most creative I've ever heard, and the melodies fit well with the rest of the music. That's right EFFORT went into making songs flow seamlessly from heavy to soft, unlike some bands who's songs sound like breakdowns were just randomly thrown into the middle of them(*cough* I See Stars *cough*) Also, Inhale Exhale does a great job in melding the two together, the last minute of the song Condemned is the most brilliant combination of a heavy breakdown and a calming melody I've ever heard. Hell, I can't even think of another band who has tried anything like that.
So there ya go, Inhale Exhale is proof that there is no such thing as a shitty genre, only shitty bands that give genres a bad name.
