Passage: Both Surfer Rosa and Steve Albini's production of the album have been influential on alternative rock, and on grunge in particular. Nirvana's Kurt Cobain cited Surfer Rosa as the basis for Nevermind's songwriting. When he first heard the album, Cobain discovered a template for the mix of heavy noise and pop he was aiming to achieve. He remarked in 1992 that he "heard songs off of Surfer Rosa that I'd written but threw out because I was too afraid to play them for anybody." Cobain hired Albini to produce Nirvana's 1993 album In Utero, primarily due to his contribution to Surfer Rosa. The Smashing Pumpkins' Billy Corgan described Surfer Rosa as "the one that made me go, 'holy shit'. It was so fresh. It rocked without being lame." Corgan was impressed by the album's drum sound, and acknowledged that The Smashing Pumpkins used to study the record for its technical elements. Musician PJ Harvey said that Surfer Rosa "blew my mind," and that she "immediately went to track down Steve Albini." Cobain listed Surfer Rosa as number 2 of the top 50 albums he thought were most influential to Nirvana's sound in his journal in 1993.People connected with the band were impressed by the record. Ivo Watts-Russell recalled: "I remember when I first heard Surfer Rosa thinking, 'I didn't know the Pixies could sound like The Fall.' That was my immediate reaction, in other words, incredibly raw." Gary Smith, who at the time was in a disagreement with the band, admitted he "was really happy that they had made such a forceful, aggressive, record." Dinosaur Jr.'s J Mascis, comparing the record to the later Pixies albums Bossanova and Trompe le Monde, said he thought that Steve Albini's production "sounded way better than the other ones."In 1991, as Pixies were recording Trompe le Monde, Albini described his impressions of Pixies during the recording of Surfer Rosa to the fan magazine Forced Exposure: "A patchwork pinch loaf from a band who at their top dollar best are blandly entertaining college rock. Their willingness to be 'guided' by their manager, their record company and their producers is unparalleled. Never have I seen four cows more anxious to be led around by their nose rings." Albini later apologized for his remarks, saying, "to this day I regret having done it. I don't think that I regarded the band as significantly as I should have.".

Passage: The white-naped xenopsaris (Xenopsaris albinucha), also known as the reed becard and white-naped becard, is a species of suboscine bird in the family Tityridae, the only member of the genus Xenopsaris. It is found in South America, in humid subtropical and tropical savanna climates in most of the countries east of the Andes: Venezuela, Brazil, Bolivia, Paraguay, Uruguay, and Argentina. Living in open woodland and other open forest habitats, it is mostly sedentary, though some populations may be migratory. The species, which is closely related to becards and tityras, was thought to be either a tyrant-flycatcher or cotinga, before it was placed in Tityridae.
The bird is 12.5 to 13 cm (4.95.1 in) in length, with whitish undersides, a black crown, and grey-brown upperparts. The sexes are similar in appearance, though the females have duller upperparts. It feeds on insects in the foliage of trees and bushes, and sometimes on the ground. Nesting occurs in a simple cup nest placed in the fork of a tree. Both parents incubate the eggs and help feed the chicks. When the chicks fledge, the parents may divide up the brood to continue helping. The species is not common and little is known about it, but it is not considered in danger of extinction, and has been classified as of least concern by the International Union for Conservation of Nature.
Question: What is the scientific name of the animal that is 12.5 to 13 cm?

Ex Output:
Xenopsaris albinucha.

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.Francois 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 Schoch.
Question: What is the last name of the person who assigned one theme to a voice, and a simultaneous theme to the orchestra in the double fugue?

Ex Output:
Reger.
