Some context: Gregory Allen Kurstin (born May 14, 1969) is an American record producer, musician and songwriter. Described as "the consummate DIY writer and producer", Kurstin has been associated with releases which have cumulatively sold more than 60 million albums worldwide. He has won five Grammy Awards, including Producer of the Year (Non-Classical) in 2017 and 2018. Kurstin co-wrote, produced and played most of the instruments on the record-breaking 2015 Adele single, "Hello".
Kurstin continued to perform with Hutcherson, Coleman, McPherson and others following his graduation. In 1994, he formed Geggy Tah with Tommy Jordan, whom he had met at an LA jam. A friend passed a demo they recorded on to David Byrne, who signed them to his label, Luaka Bop. "They incorporate so many disparate elements into their sound that one senses a new sensibility afoot", Byrne said in 1997. Geggy Tah released their debut album Grand Opening in 1994; Kurstin played bass, clavinet, guitar, organ, piano, synthesizers and drums, and was credited as a songwriter, producer, programmer, and backup vocalist. In 1996 the band released Sacred Cow. It included the song "Whoever You Are", which became a hit in 2001, after it was used in a television spot for Mercedes Benz. As the song ascended the charts, Geggy Tah released their final album, Into the Oh. In addition to playing with Geggy Tah, Kurstin did session work, one-offs and tours with artists including Beck, Ben Harper, and the Red Hot Chili Peppers. In 2001, he released an album under the name Action Figure Party on the Verve-affiliated label Blue Thumb Records. Flea, Sean Lennon, Soul Coughing's Yuval Gabay as well as musicians who performed with Beck, Air, Gil-Scott Heron and Garbage appeared on the record. Kurstin signed a worldwide publishing deal with EMI (now Sony/ATV) in 2002. While he had consistently written songs since the age of 12, he intensified his efforts, working "day and night, pumping out songs". In addition to writing on his own, he collaborated with songwriters and artists including Sia, whom he met through Beck in 2003.

Question: Polly Jean Harvey was born on 9 October 1969 in Bridport, Dorset, the second child of Ray and Eva Harvey, who owned a stone quarrying business, and grew up on the family's farm in Corscombe. During her childhood, she attended school in nearby Beaminster, where she received guitar lessons from folk singer-songwriter Steve Knightley, and her parents introduced her to music that would later influence her work, including blues music, Captain Beefheart and Bob Dylan. Her parents were avid music fans and regularly arranged get-togethers and small gigs; among their oldest friends was Ian Stewart. As a teenager, Harvey began learning saxophone and joined an eight-piece instrumental group Bologne, based in Dorset.

As Harvey embarked on her solo career, she explored collaborations with other musicians. In 1995 she released her third studio album, To Bring You My Love, featuring former bandmate John Parish, Bad Seeds multi-instrumentalist Mick Harvey and French drummer Jean-Marc Butty, all of whom would continue to perform and record with Harvey throughout her career. The album was also her first material to be produced by Flood. Simultaneously a more blues-influenced and more futuristic record than its predecessors, To Bring You My Love showcased Harvey broadening her musical style to include strings, organs and synthesisers. Rolling Stone said in its review that "Harvey sings the blues like Nick Cave sings gospel: with more distortion, sex and murder than you remember. To Bring You My Love was a towering goth version of grunge." During the successive tours for the album, Harvey also experimented with her image and stage persona. The record generated a surprise modern rock radio hit in the United States with its lead single, "Down by the Water." Three consecutive singles -- "C'mon Billy", "Send His Love to Me" and "Long Snake Moan" -- were also moderately successful. The album was a commercial success selling one million copies worldwide including 370,000 in the United States. It was also certified Silver in the United Kingdom within seven months of its release, having sold over 60,000 copies. In the United States, the album was voted Album of the Year by The Village Voice, Rolling Stone, USA Today, People, The New York Times and the Los Angeles Times. Rolling Stone also named Harvey 1995's Artist of the Year and Spin ranked the album third in The 90 Greatest Albums of the '90s, behind Nirvana's Nevermind (1991) and Public Enemy's Fear of a Black Planet (1990). In 1996, following the international success of To Bring You My Love and other collaborations, Harvey began composing material that would end up on her fourth studio album, during what she referred to as "an incredibly low patch." The material diverged significantly from her former work and introduced electronica elements into her song-writing. During recording sessions in 1997 original PJ Harvey Trio drummer Rob Ellis rejoined Harvey's band, and Flood was hired again as producer. The sessions, which continued into April the following year, resulted in Is This Desire? (1998). Though originally released to mixed reviews in September 1998, the album was a success and received a Grammy Award nomination for Best Alternative Music Performance. The album's lead single, "A Perfect Day Elise," was moderately successful in the United Kingdom, peaking at number 25 on the UK Singles Chart, her most successful single to date.

Using a quote from the above article, answer the following question: What are the materials he was composing?

Some context: Osceola was named Billy Powell at birth in 1804 in the Creek village of Talisi. now known as Tallassee, Alabama, in current Elmore County. "The people in the town of Tallassee...were mixed-blood Native American/English/Irish/Scottish, and some were black. Billy was all of these."
After Osceola's death, army doctor Frederick Weedon persuaded the Seminole to allow him to make a death mask of Osceola, this being a European-American custom at the time for prominent people. Later he removed Osceola's head and embalmed it. For some time, Weedon kept the head and a number of personal objects Osceola had given him. Later, Weedon gave the head to his son-in-law Daniel Whitehurst. In 1843, Whitehurst sent the head to Valentine Mott, a New York physician. Mott placed it in his collection at the Surgical and Pathological Museum. It was presumably lost when a fire destroyed the museum in 1866. Some of Osceola's belongings are still held by the Weedon family, while others have disappeared. Captain Pitcairn Morrison sent the death mask and some other objects collected by Weedon to an army officer in Washington. By 1885, the death mask and some of Osceola's belongings had arrived in the anthropology collection of the Smithsonian Institution, where they are still held. In 1966, Miami businessman Otis W. Shriver claimed he had dug up Osceola's grave and put his bones into a bank vault to rebury them at a tourist site at the Rainbow Springs. Shriver traveled around the state in 1967 to gather support for his project. Archaeologists later proved that Shriver had dug up animal remains; Osceola's body was still in its coffin. In 1979 the Seminole Nation of Oklahoma bought Osceola's bandolier and other personal items from a Sotheby's auction. Because of the chief's significance, over time some people have created forgeries of Osceola's belongings. Rumors persist that his embalmed head has been found in various locations.
Did Weedon keep the mask?
A:
For some time, Weedon kept the head and a number of personal objects Osceola had given him.
