question: Grinderman and DIIV, are bands of which mutual genre?
answer: rock
context: Title: Morbid Angel
  Passage: 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.
  Title: Emo
  Passage: 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.

  Title: Stoner rock
  Passage: Stoner rock or stoner metal is a rock music fusion genre that combines elements of heavy metal and/or doom metal with psychedelic rock and acid rock.

  Title: List of avant-garde metal artists
  Passage: This is a list of avant-garde metal artists, regional scenes, and record labels.  Avant-garde metal or avant-metal, also known as experimental metal, is a subgenre of heavy metal music loosely defined by use of experimentation and characterized by the use of innovative, avant-garde elements, large-scale experimentation, and the use of non-standard and unconventional sounds, instruments, song structures, playing styles, and vocal techniques.  It evolved out of progressive rock and various forms of metal, including extreme metal, particularly the extreme subgenre death metal.  Some early examples are the King Crimson releases "Larks' Tongues in Aspic" and "Red" in 1973 and 1974 respectively, and the 1976 Led Zeppelin album "Presence".  The genre emerged in the early 1980s through the efforts of bands such as Celtic Frost and Voivod, who pioneered the genre.  Other pioneers of avant-garde metal include Boris, Earth, Helmet, maudlin of the Well, Neurosis, Sunn O))), and Mr. Bungle.  In the late 1990s, Misanthropy Records emerged as a promoter of Norwegian avant-garde metal until it folded in 2000, and, according to Jeff Wagner, in the late 1990s and early 2000s, a so-called "new wave of avant-garde metal" was spearheaded by The End Records.  Some other record labels which promote avant-garde metal are Aurora Borealis, The Flenser, Holy Records, Hydra Head Records, Ipecac Recordings, Napalm Records, the Relapse Entertainment imprint of Relapse Records, Seventh Rule Recordings, and Southern Lord Records.  In the United States, local avant-garde metal scenes have emerged in the San Francisco Bay Area, with bands such as Giant Squid, Grayceon, and Ludicra, Boston, with bands such as Isis, Kayo Dot, and maudlin of the Well and Seattle.
