Question: Passage: The name Spiderland originates from McMahan's younger brother, who thought that the record sounded "spidery". The album's black-and-white cover photograph, which depicts the members of the band (Brashear, McMahan, Walford and Pajo, from left to right) treading water in the lake of an abandoned quarry, was taken by Will Oldham. An article in The Stranger credited the cover for creating a mystique surrounding Slint, noting "[m]ost people only had seen Slint as four heads floating in a Kentucky quarry on Spiderland's cover. Listeners pondered the band's sparsely adorned black-and-white covers as if they were runes bearing secrets." Chris Gaerig of the Michigan Daily wrote, "the cover of Slint's masterful Spiderland captures the joyous fear and violence of the album so precisely it shakes souls. The group—submerged in a lake to their chins with deranged smiles—seems to be stalking you, hovering out of the black-and-white façade." Several other promotional images have been taken from the same photo session with Oldham.A photo of a spider taken by Noel Saltzman is used on the back cover, reflecting the album's title. The inside sleeve contains the message "interested female vocalists write 1864 douglas blvd. louisville, ky. 40205". McMahan confirmed that this message was serious, and said "We did get some responses and we did listen to CDs and tapes. We didn't end up doing anything immediately, so that idea of adding someone sort of fell by the wayside." The message "this recording is meant to be listened to on vinyl" is printed on some CD issues of Spiderland, demonstrating Slint's preference of analog audio devices. 
Question: What is the name of the band whose members are depicted on Spiderland's black-and-white cover photograph?

Answer: Slint.


Question: Passage: Paul Helfeld (also given as Hefeld), aged 21 in 1909, and Jacob Lepidus (also reported as Lapidus), who was 25 the same year, were Jewish-Latvian immigrants. They had been members of the Latvian Socialist Party and, although they had not held positions of responsibility, they had smuggled revolutionary literature into Russia for the party. The pair had been living in Paris in 1907, along with Lepidus's brother Paul, a revolutionary bomber who went under the nom de guerre "Strygia"; Jacob was described in The Times as a "member of a notorious Russian revolutionary family". On 1 May 1907 Paul Lepidus was killed when a bomb he was carrying to assassinate Armand Fallières, the President of France, exploded prematurely. Lepidus and Helfeld fled the country and lived in Scotland for a year, before moving to Tottenham.Both men joined a small group of Latvian agitators living in north London; according to other members of the group, the pair had criminal records and had joined as a cover for the robberies they carried out. Lepidus was employed, briefly, at a furniture factory, while Helfeld took a job at the Schnurmann rubber factory in Tottenham. Helfeld refused to give his name when he joined the company, so he was listed on the time sheets as "Elephant" in reference to his bulk. Situated on the corner of Tottenham High Road and Chesnut Road, the factory sat opposite Tottenham Police Station, which was under the control of the Metropolitan Police.Special Branch suspected another individual, the Russian revolutionary Christian Salnish, of having organised the robbery. Salnish, who often went under the name Jacob Fogel, had been an active revolutionary since the age of 13. He participated in the 1905 Russian Revolution and afterwards helped to build resistance groups in the Baltic states and Saint Petersburg, then the capital of Imperial Russia. Special Branch suspected a political element to the crime based on Salnish's involvement, but as both Helfeld and Lepidus died during the chase, the motivation for the crime was never established. 
Question: What is the first name of Paul's brother?

Answer: Jacob.


Question: Passage: In 1955, Paul Hindemith revised the work to achieve more clarity. According to Wolfgang Rathert, Hindemith "sought to moderate Reger's 'uncontrolled invention'", while Kirshnit described Reger's original scoring as "gloriously polychromatic". Hindemith "thinned" the orchestra, especially the horns. In Reger's scoring, the organ reinforced the voices throughout the piece, resulting in a lack of clarity for the polyphonic passages. Hindemith used the organ only for climaxes. In the double fugue, he assigned one theme to a voice, but the other simultaneous theme to the orchestra. Hindemith's approach, which enables more analytical listening, seems justified by Reger's own scoring of later compositions which were more refined and focused. It is probably due to his version that Der 100. Psalm enjoyed continuous presence in concert halls, while other works by Reger were neglected.François Callebout wrote an organ version that was published in 2004 by Dr. J. Butz. Gabriel Dessauer explains in the preface that Reger's work was conceived for oratorio choirs of up to 500 singers at the beginning of the 20th century. The organ version enables smaller choirs to perform the music. This version was premiered in 2003 by the Reger-Chor in St. Bonifatius, Wiesbaden, the parish to which the composer belonged during his studies in Wiesbaden. The organ was played by Ignace Michiels, organist at the St. Salvator Cathedral in Bruges.Hanns-Friedrich Kaiser, KMD (director of church music) in Weiden, where Reger grew up, wrote a version for choir and organ, which he conducted at the opening of the festival Reger-Tage at the church St. Michael on 16 September 2012, with organist Michael Schöch. 
Question: What is the full name of the person who conducted at the opening of the festival?

Answer:
Hanns-Friedrich Kaiser.
