Problem: Neutral Milk Hotel was an American indie rock band formed in Ruston, Louisiana by singer, guitarist, and songwriter Jeff Mangum in the late 1980s. The band is noted for its experimental sound, abstract lyrics and eclectic instrumentation. The first release under the Neutral Milk Hotel moniker was the 1994 EP Everything Is, a short collection of tracks featuring Mangum.

Jeff Mangum, along with high-school friends Will Cullen Hart and Bill Doss, formed The Olivia Tremor Control, with Mangum appearing on their first release, the California Demise 7".  Prior to recording for friends under the Neutral Milk Hotel moniker, Mangum recorded a few cassettes under the name Milk; the most well-known of these tapes was called Pygmie Barn in E Minor. These are the earliest known recordings that Mangum initiated and executed himself. There were only an estimated dozen or so copies ever made of this tape, none of which has been made public. It was revealed c. 2006 on the Elephant 6 online forums that another tape under said name, entitled Beauty, was released, along with several recordings under the name Ruby Bulbs (also a song dating from that era, perhaps the only Milk song to be played by Neutral Milk Hotel).  Neutral Milk Hotel began simply as a recording project for Mangum, in the late 1980s. He produced several demo cassettes, among them 1991's Invent Yourself a Shortcake, 1992's Beauty (not to be confused with the earlier cassette), and 1993's Hype City Soundtrack, along with two more from this period, seemingly unnamed. Although easily found on the Internet, these demos capture the project at a very embryonic stage: songs are played in between various sound collages and tape experiments, one of which consists only of a six-minute conversation between Mangum and Hart. Another track, "Digestion Machine", features a varied collage of voices answering the question asked by Mangum, "What does the digestion machine mean to you?". The more accessible "Synthetic Flying Machine", also titled "Up and Over", later became "The King of Carrot Flowers Pt. 3" on In the Aeroplane Over the Sea.  During this period, Mangum was wandering the country, staying with friends, and in a state of perpetual unemployment. It was in these circumstances that the band's first formal releases took shape. Strictly speaking, however, the 'band' usually consisted of Mangum and whoever else was present at the time. This is obvious on Neutral Milk Hotel's first release, a 7" record entitled Everything Is, recorded when Mangum was spending time in Seattle, Washington, released on Cher Doll Records in 1993.

Problem: Meat Beat Manifesto, often shortened as Meat Beat, Manifesto or MBM, is an electronic music group originally consisting of Jack Dangers and Jonny Stephens, and formed in 1987 in Swindon, United Kingdom. The band, fronted by Dangers (the only permanent member), has proven versatile over the years, experimenting with techno, dubstep, drum and bass, IDM, industrial, dub and jazz fusion while touring the world and influencing major acts such as Nine Inch Nails, The Chemical Brothers and The Prodigy. Some of the band's earlier work has been credited with influencing the rise of the trip hop, big beat, and drum and bass genres.

Dangers and Stephens had formed the English pop group Perennial Divide in 1986 with Paul Freeguard and released the first few Meat Beat Manifesto singles as a side project. They left Perennial Divide in 1988 to record a full Meat Beat album. The tapes of what would have been the debut MBM album were claimed to have been destroyed in a studio fire before it could be released (detailed in a publicity statement). The former founder of Sweat Box Records (Rob Deacon) said that the fire never happened. Jack Dangers confirmed the story of the fire in a 2010 interview. The pair then recorded the LP Storm The Studio, which got them pigeonholed as an industrial act because Sweat Box Records sold the rights to the LP to Wax Trax Records for release in the United States. In response, they released 99%, which was more techno-influenced, in May 1990. In August they released Armed Audio Warfare, which was an effort to re-create the lost tracks of the would-be debut album.  The band's live show was conceived as an intense audio-visual experience, with dancers, led by choreographer Marcus Adams, in costumes and sets designed by artist Craig Morrison and video clips accompanying live instruments, sequenced electronic instruments, and live DJing. In the United States, they opened for Nine Inch Nails on their debut national tour in 1990. In 1991, they performed at The Limelight in Manhattan. Despite his contributions being nonmusical in nature, Adams was credited as a full band member and appeared in many of the band's record sleeves and promo photos until the release of Satyricon in 1992. Adams also appeared in several of MBM's early videos, such as "Strapdown" and "Psyche-Out".  1992's Satyricon continued to show Meat Beat adopting a more mainstream electronic sound, crediting influences of such newly popular dance bands as Orbital, The Shamen, and The Orb, all of whom had either remixed or been remixed by MBM. The album produced the hits "Mindstream" and "Circles". "Original Control (Version 2)", renamed "I Am Electro" in later compilations, is the best-known track from the album, featuring samples of recordings from the 1939 World's Fair exhibit Elektro The Robot, and was the opening song in MBM's 2005-2006 tour.
