Passage: Pod was released in the UK on May 29, 1990 by 4AD. Watts-Russell planned the date to be not too close to the release of the Pixies' Bossanova two and a half months later, for more effective publicity of both albums.  Watts-Russell believed the album would be better suited to a US independent distribution label rather than the Pixies' American distributor Elektra, and licensed Pod to Rough Trade America. When this division of Rough Trade went bankrupt, Elektra assumed distribution of Pod in the US. Deal has noted that the Breeders did not receive any royalties from initial US sales because of Rough Trade's bankruptcy.The album was widely anticipated by the British music press due to the involvement of Deal and Donelly—known from their highly regarded work with the Pixies and Throwing Muses, respectively—and Albini, who likewise had a strong reputation for his previous engineering work. It reached number 22 in the UK, where it was promoted by a full-page ad in Melody Maker, and number 73 in the Netherlands. Pod sold moderately well, although Deal has noted it "never sold [anything]" compared to their next album, Last Splash (1993), which was certified platinum in the US and silver in the UK.Deal took the idea for the album's title from a painting that she saw in Boston; for her, the word "pod" evoked a uterus, which Wiggs has noted relates to the theme of fertility and the group's name. The cover art was designed by longtime 4AD album designer Vaughan Oliver and employs photography by Kevin Westenberg. Oliver, in an attempt to seduce Deal, whom he believed would appreciate the humor, attached a belt of dead eels over his underwear, which he intended as phallic symbols. He performed a fertility dance, while Westenberg took pictures of him using a long exposure to achieve the blurring and other visual effects. 
Question: What is the name of the individual known from their highly regarded work with Throwing Muses?
Donelly.

Passage: During the latter half of 2002, Sasha collaborated with big beat artist Junkie XL on the single "Breezer". Junkie XL, along with Charlie May, also assisted Sasha on his second album of original material, Airdrawndagger.  Airdrawndagger took several years to produce due to Sasha's desire for the album to be "as near to perfection as possible."  That March, Sasha suffered a perforated eardrum in a traffic accident, further delaying the album's production. Though the accident temporarily impaired his hearing, he drew inspiration for the album from his ordeal.  Airdrawndagger was finally released, in August 2002, to much fanfare. However, the album was "received with a lot of head scratching", according to Sasha, which he attributed to its unexpected mix of genres. The album did not feature the heavier "club sound" of Sasha's previous mix albums, bearing a closer resemblance to ambient music.  Airdrawndagger generally received favorable reviews, though critics noted that it was not as consistent and well produced as his DJ mixes. Sasha himself described it as "a selfish, slightly self-indulgent record", though he maintains that he is "happy with it to this day".  Some critics, however, called it "sleepy"; E!Online described it as being "more in league with Yanni than Moby".  To encourage listeners' interest, Sasha held an amateur remix contest for the album's single, "Wavy Gravy".  Due to the contest's success, Sasha released all the tracks from Airdrawndagger on his website, so that fans could download and create their own versions.After the release of Airdrawndagger, Sasha took the young DJ James Zabiela "under his wing". He introduced Zabiela to the CDJ1000 turntable, and signed Zabiela to the Excession talent agency.  The two toured the United States together, which extended Sasha's influence to already-popular American DJs such as Kimball Collins.
In 2004, Sasha signed with Global Underground to produce another mix album. However, he found the process of creating a standard mix album unrewarding, and decided to apply his production and DJing skills to a mix compilation that resembled a "real" album—that is, one featuring original material.  Sasha's next studio album, Involver, was "a fusion of mix album and production record", consisting entirely of Sasha's reworkings of tracks by other artists.  "I tried to take all the separate sounds to all the tracks [and recombine them]", he later explained, "and it allowed me to mix the tracks together on a much deeper level."  He accomplished this by sequencing the album using Ableton Live and Logic Pro.  Ableton Live is a music loop-based software package that Sasha uses to engineer tracks in real-time, whereas he used Logic Pro primarily for premeditated edits to audio tracks. 
Question: What is the name of the person whose hearing was temporarily impaired?
Sasha.

Passage: On 10 June 1859, the 19-year-old Tchaikovsky graduated as a titular counselor, a low rung on the civil service ladder. Appointed to the Ministry of Justice, he became a junior assistant within six months and a senior assistant two months after that. He remained a senior assistant for the rest of his three-year civil service career.Meanwhile, the Russian Musical Society (RMS) was founded in 1859 by the Grand Duchess Elena Pavlovna (a German-born aunt of Tsar Alexander II) and her protégé, pianist and composer Anton Rubinstein. Previous tsars and the aristocracy had focused almost exclusively on importing European talent. The aim of the RMS was to fulfill Alexander II's wish to foster native talent. It hosted a regular season of public concerts (previously held only during the six weeks of Lent when the Imperial Theaters were closed) and provided basic professional training in music. In 1861, Tchaikovsky attended RMS classes in music theory taught by Nikolai Zaremba at the Mikhailovsky Palace (now the Russian Museum). These classes were a precursor to the Saint Petersburg Conservatory, which opened in 1862. Tchaikovsky enrolled at the Conservatory as part of its premiere class. He studied harmony and counterpoint with Zaremba and instrumentation and composition with Rubinstein.The Conservatory benefited Tchaikovsky in two ways. It transformed him into a musical professional, with tools to help him thrive as a composer, and the in-depth exposure to European principles and musical forms gave him a sense that his art was not exclusively Russian or Western. This mindset became important in Tchaikovsky's reconciliation of Russian and European influences in his compositional style. He believed and attempted to show that both these aspects were "intertwined and mutually dependent". His efforts became both an inspiration and a starting point for other Russian composers to build their own individual styles. 
Question: What is the name of the person who studied harmony and counterpoint with Zaremba?

Tchaikovsky.
