Passage: English-Tamil musician M.I.A. (Mathangi "Maya" Arulpragasam) released her second album Kala in 2007, which achieved widespread critical acclaim, and was certified gold in the United States and silver in the United Kingdom. Six months after giving birth to her son Ikyhd in February 2009, she began composing and recording her third studio album in a home studio section of the Los Angeles house she had bought with her partner Ben Bronfman. She used instruments such as the portable dynamic-phrase synthesizer Korg Kaossilator to compose. She took the beat machine and began recording atop Mayan pyramids in Mexico. Much of the work on the album was undertaken at her house in Los Angeles, in what she called a "commune environment", before it was completed in a rented studio in Hawaii. She collaborated with writer-producer Blaqstarr because, in her opinion, "he simply makes good music". M.I.A.'s collaboration with Derek E. Miller of Sleigh Bells on the track "Meds and Feds" prompted her subsequent signing of the band to her label N.E.E.T., and according to Miller, this experience gave him the confidence to record the band's debut album Treats.Her creative partnership with the comparatively unknown Rusko grew from a sense of frustration at what she saw as her now more mainstream associates suggesting sub-standard tracks due to their busy schedules. Diplo worked on the track "Tell Me Why", but at a studio in Santa Monica rather than at the house. He claimed in an interview that, following the break-up of his personal relationship with M.I.A. some years earlier, he was not allowed to visit the house because "her boyfriend really hates me".Tracks for the album were whittled down from recording sessions lasting up to 30 hours. Producer Rusko, who played guitar and piano on the album, described the pair getting "carried away" in the studio, appreciating the "mad distorted and hectic" sound they were able to create. Rusko said "She's got a kid, a little one year old baby, and we recorded his heart beat. We'd just think of crazy ideas". Rusko has described M.I.A. as the best artist he has ever worked with, saying that she had "been the most creative and I really had a good time making music with her". 
Question: What is the name of the person that had their hear beat recorded?

Ex Output:
Ikyhd.

Passage: By 1957 Grainger's physical health had markedly declined, as had his powers of concentration. Nevertheless, he continued to  visit Britain regularly; in May of that year he made his only television appearance, in a BBC "Concert Hour" programme when  he played "Handel in the Strand" on the piano. Back home, after  further surgery  he recovered sufficiently to undertake a modest winter concerts season. On his 1958 visit to England he met Benjamin Britten, the two having previously maintained a mutually complimentary correspondence. He agreed to visit Britten's Aldeburgh Festival in 1959, but was prevented by illness. Sensing that death was drawing near, he made a new will, bequeathing his skeleton "for preservation and possible display in the Grainger Museum". This wish was not carried out.Through the winter of 1959–60 Grainger continued to perform his own music, often covering long distances by bus or train; he would not travel by air. On 29 April 1960 he gave his last public concert, at Dartmouth College in Hanover, New Hampshire, although by now his illness was affecting his concentration. On this occasion his morning recital  went well, but his conducting in the afternoon  was, in his own words, "a fiasco".  Subsequently confined to his home, he continued to revise his music and arrange that of others; in August he informed Elsie  that he was working on an adaptation of one of Cyril Scott's early songs.  His last letters, written from hospital in December 1960 and January 1961, record  attempts to work, despite failing eyesight and hallucinations: "I have been trying to write score for several days. But I have not succeeded yet."Grainger died in the White Plains hospital on 20 February 1961, at the age of 78. His body was flown to Adelaide where, on 2 March, he was buried in the Aldridge family vault in the West Terrace Cemetery, alongside Rose's ashes. Ella survived him by 18 years; in 1972, aged 83, she married a young archivist, Stewart Manville. She died at White Plains on 17 July 1979. 
Question: What is the last name of the person who left his skeleton in his will for the Grainger Museum?

Ex Output:

Grainger.
