Context paragraphs:
Emo: Emo is a genre of rock music characterized by an emphasis on emotional expression, sometimes through confessional lyrics.  It emerged as a style of post-hardcore from the mid-1980s hardcore punk movement of Washington, D.C., where it was known as emotional hardcore or emocore and pioneered by Washington, D.C. hardcore bands such as Rites of Spring and Embrace.  However, as the genre was taken up by a new generation of musicians in the early 1990s, its sound and meaning shifted and changed and it was reinvented as a style of indie rock and pop punk by bands such as Jawbreaker, Sunny Day Real Estate, Weezer, and Jimmy Eat World.  By the mid-1990s, numerous emo acts such as Braid, The Promise Ring, and the Get Up Kids emerged in the Midwestern and Central United States, and several independent record labels began to specialize in the genre.  Meanwhile, a more aggressive style of emo, screamo, had also emerged, pioneered by the San Diego bands Heroin and Antioch Arrow.

Morbid Angel: Morbid Angel is an American death metal band based in Tampa, Florida formed in 1983 by guitarist and sole remaining original member Trey Azagthoth, original vocalist and bassist Dallas Ward, and original drummer Mike Browning.  Widely considered as one of the most influential bands in the genre and important in the transition of death metal from its thrash metal roots, they were one of the first bands to incorporate guttural vocals, up-tempo blast beats, atonality in guitar playing, multiple tempo changes and dark atmosphere.  They have been described as one of "the most influential and emulated bands in death metal", alongside Cannibal Corpse, and have been cited as an influence by many later bands.  They were also the first death metal band to experience mainstream success in connection with being signed to Giant Records in 1992, heavy rotation of their music videos on MTV, and having the music video for the song "God of Emptiness" shown on an episode of "Beavis and Butt-head".  Their first four albums are considered classics in the genre.
