A made up music genre. By the media to describe melodic hardcore punk bands,that wrote personel and sad lyrics or song in a whiny style of voice. And of course everybody likes to say that the beginning of emocore started with rites of spring. They actually just are a bad sounding post-hardcore band. In the mid 80s they wrote more mellodic songs with personel lyrics. When they played shows some of crowd thought that the songs were so sad that they cried like they were the beatles. These people were called emo. In the 90s the band jawbreaker wrote a sad little song about getting drunk instead of kissing a girl. And got called emo. Sunny day real estate though may be the only emo band because of their sound but only for one song seven. Then the media made it out like to be emo write a song like jawbreaker and sound like sdre. Sunny day real estate is mainly a band that mixes grunge and hardcore. They did one whiny record and that was it. There is no band that comes out saying that there emo. But the only band I know that sounds simuler are to sdre is taking back sunday. But there not emo either.
