Background: The Apples in Stereo, styled as The Apples in stereo, are an American rock band associated with Elephant Six Collective, a group of bands also including Neutral Milk Hotel and The Olivia Tremor Control. The band is largely a product of lead vocalist/guitarist/producer Robert Schneider, who writes the majority of the band's music and lyrics. Currently, The Apples in Stereo also includes longstanding members John Hill (rhythm guitar) and Eric Allen (bass), as well as more recent members John Dufilho (drums), John Ferguson (keyboards), and Ben Phelan (keyboards/guitar/trumpet). The band's sound draws comparisons to the psychedelic rock of The Beatles and The Beach Boys during the 1960s, as well as to bands such as Electric Light Orchestra and Pavement, and also draws from lo-fi, garage rock, new wave, R&B, bubblegum pop, power pop, punk, electro-pop and experimental music.
Context: Several conflicts would lead Parfitt to leave the band in early 1994. John Hill, a former bandmate of McIntyre's, would join the band as a rhythm guitarist while Schneider began to grow more comfortable playing lead guitar. It was also at this time that Schneider began to take stronger creative control of the band, shifting its sound from its stronger rock qualities to a spacier pop sound. The band started work on a debut full-length album, but it instead became Hypnotic Suggestion, a second EP. However, after SpinART Records offered to buy the band an 8-track in return for an album, new plans for an LP arose.  In mid-1994, after Hypnotic Suggestion, McIntyre would be the second to leave the band, due to a number of personal distresses as well as stylistic changes that arose with Parfitt's departure. Having great difficulty finding a new permanent bassist, the band would rotate a number of frequent bass contributors, including Jeff Mangum of Neutral Milk Hotel, Kurt Heasley of The Lilys, Kyle Jones, Joel Richardson, and Joel Evans. Jim McIntyre would also occasionally guest on bass. This continued to be the makeup of the band as they toured the country in late 1994, recording the first half of their new album in Glendora, California. In early 1995, the band finished the album, Fun Trick Noisemaker, at Kyle Jones's house (the birthplace of Schneider's Pet Sounds Studio).  Now with a full-length LP to support, the band began touring again. Eric Allen, whom the band had previously auditioned as a guitarist after the departure of Chris Parfitt, joined the band as a much welcomed permanent bassist. Late 1995, Schneider relocated Pet Sounds Studio to Jim McIntyre's house. McIntyre continued to be involved in the recording and engineering of the band's albums until the mid-2000s.  A significantly different band from the original 1992 four-piece, the official name of the band gradually became "The Apples in Stereo", with the "in stereo" usually somewhat under-emphasized, whether in lower-case or in parentheses. Schneider described this in an interview: "It's very clearcut, actually: we're The Apples, the music's in stereo. It's not actually the band name - it's a step back from it, a band name once removed. We're The Apples, in stereo. Kind of like a TV show, 'in stereo!' That always seemed to be a really big deal, that it was in stereo." McIntyre later remarked, "It's cool the name changed cause the Apples and the Apples in Stereo were really two different entities."
Question: Who else was a member of the band?
Answer: Parfitt

Problem: Background: Frederick II (26 December 1194 - 13 December 1250; Sicilian: Fidiricu, Italian: Federico, German: Friedrich) was King of Sicily from 1198, King of Germany from 1212, King of Italy and Holy Roman Emperor from 1220 and King of Jerusalem from 1225. His mother Constance was Queen of Sicily and his father was Henry VI of the Hohenstaufen dynasty. Frederick's reign saw the Holy Roman Empire reaching its all time territorial peak.
Context: Historians rate Frederick II as a highly significant European monarch of the Middle Ages. This reputation was present even in Frederick's era. Lansing and English, two British historians, argue that medieval Palermo has been overlooked in favor of Paris and London:  One effect of this approach has been to privilege historical winners, [and] aspects of medieval Europe that became important in later centuries, above all the nation state.... Arguably the liveliest cultural innovation in the 13th century was Mediterranean, centered on Frederick II's polyglot court and administration in Palermo.... Sicily and the Italian South in later centuries suffered a long slide into overtaxed poverty and marginality. Textbook narratives therefore focus not on medieval Palermo, with its Muslim and Jewish bureaucracies and Arabic-speaking monarch, but on the historical winners, Paris and London.  Modern medievalists no longer accept the notion, sponsored by the popes, of Frederick as an anti-Christian. They argue that Frederick understood himself as a Christian monarch in the sense of a Byzantine emperor, thus as God's "viceroy" on earth. Whatever his personal feelings toward religion, certainly submission to the pope did not enter into the matter in the slightest. This was in line with the Hohenstaufen Kaiser-Idee, the ideology claiming the Holy Roman Emperor to be the legitimate successor to the Roman Emperors.  20th century treatments of Frederick vary from the sober (Wolfgang Sturner) to the dramatic (Ernst Kantorowicz). However, all agree on Frederick II's significance as Holy Roman Emperor. In the judgment of British historian Geoffrey Barraclough, Frederick's extensive concessions to German princes--which he made in the hopes of securing his base for his Italian projects--undid the political power of his predecessors and postponed German unity for centuries.  However, the modern approach to Frederick II tends to be focused on the continuity between Frederick and his predecessors as Kings of Sicily and Holy Roman Emperors, and the similarities between him and other thirteenth-century monarchs. David Abulafia, in a biography subtitled "A Medieval Emperor," argues that Frederick's reputation as an enlightened figure ahead of his time is undeserved, and that Frederick was mostly a conventionally Christian monarch who sought to rule in a conventional medieval manner.
