Problem: 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: What does EP mean in regards to music?
Answer: 

Problem: Background: Legion (David Charles Haller) is a fictional superhero appearing in American comic books published by Marvel Comics. He is the mutant son of Professor Charles Xavier and Gabrielle Haller. Legion takes the role of an antihero who has a severe mental illness including a form of dissociative identity disorder, in which each of his alternate personas controls one of his many superpowers. The television series Legion premiered on FX network in 2017.
Context: When Mystique tracked down David years later to get revenge for "his" murder of Destiny, he awakened with his fractured mind healed. David had a new goal, to help his father realize his dream of human-mutant coexistence by killing Magneto, Xavier's greatest opponent, before he had a chance to amass power. He traveled twenty years into the past, when Xavier and Magneto were orderlies at the mental hospital. In the process, he loses his memory. Magneto then accidentally triggers his memory, causing David to go on a rampage, attacking Magneto and revealing the existence of mutants to the public decades too early. Several X-Men who were pulled back in time with him were unable to prevent him from attacking Magneto. Xavier, however, leaped into the path of the psi-knife (the focused totality of Legion's psionic powers) and was killed in Magneto's place, causing the formation of the Age of Apocalypse timeline.  Due to being trapped in the past by David's actions, Bishop enlisted the aid of the new reality's X-Men to travel back in time to confront Legion again. Bishop seized Legion's psi-blade and drove it into his own chest, allowing Legion to see the future that he caused. In his last moments, David apologized for what he did. David's mother, Gabrielle Haller, described having a "maternal loss" afterward, implying she miscarried before giving birth to David.  While David was considered deceased, some of his alternate personalities remained trapped between life and death, manifesting as spirits. When the spirits started terrorizing Israel, Excalibur was called to stop them. After learning that the spirits were refusing death, Meggan used her empathy to calm their rage, convincing them to go "towards the light."
