Passage: There were no documentaries or compilation albums in the wake of Drake's death. His public profile remained low throughout the 1970s, although his name appeared occasionally in the music press. By this time, his parents were receiving an increasing number of fans and admirers as visitors to the family home. Island Records, following a 1975 NME article written by Nick Kent, stated they had no plans of repackaging Drake's albums, but in 1979 Rob Partridge joined Island Records as press officer and commissioned the release of the Fruit Tree box set. The release compiled the three studio albums, the four tracks recorded with Wood in 1974, and an extensive biography written by the American journalist Arthur Lubow. Although sales were poor, Island Records never deleted the three albums from its catalogue.By the mid-1980s, Drake was being cited as an influence by musicians such as Peter Buck of R.E.M. and Robert Smith of the Cure; Smith credited the origin of his band's name to a lyric from Drake's song "Time Has Told Me" ("a troubled cure for a troubled mind"). Drake gained further exposure in 1985 with the release of the Dream Academy's hit single "Life in a Northern Town", which included a dedication to Drake on its sleeve. In 1986, a biography of Drake was published in Danish; it was translated, updated with new interviews, and published in English in February 2012. Drake's reputation continued to grow, and by the end of the 1980s, his name was appearing regularly in newspapers and music magazines in the United Kingdom; he had come to represent a "doomed romantic hero".On 20 June 1998, BBC Radio 2 broadcast a documentary, Fruit Tree: The Nick Drake Story, featuring interviews with Boyd, Wood, Gabrielle and Molly Drake, Paul Wheeler, Robert Kirby and Ashley Hutchings, and narrated by Danny Thompson. In early 1999, BBC2 aired a 40-minute documentary, A Stranger Among UsIn Search of Nick Drake. The following year, Dutch director Jeroen Berkvens released the documentary A Skin Too Few: The Days of Nick Drake, featuring interviews with Boyd, Gabrielle Drake, Wood and Kirby. Later that year, The Guardian placed Bryter Layter number one in its "Alternative Top 100 Albums Ever" list. In November 2014, Gabrielle published a biography of Drake.

Passage: Slint formed in 1987 in Louisville, Kentucky, from the remnants of the punk rock band Squirrel Bait; the founding members included Brian McMahan (guitar, vocals), David Pajo (guitar), Britt Walford (drums) and Ethan Buckler (bass guitar). The band's debut album, the Steve Albini-produced Tweez, was released on the group's self-owned label Jennifer Hartman Records and Tapes. The album's sound has been described as a combination of "scratchy guitars, thumping bass lines and hard hitting drums". Buckler promptly left the band out of dissatisfaction with Albini's production, and was replaced with Todd Brashear. The band's second recording was for the instrumental extended play Slint, which included a new version of "Rhoda" from Tweez. The EP, which would not be released until 1994, was a departure from Tweez's sound and reflected the band's new musical direction.After the band ended its brief tour in support of Tweez, most of its members attended college. Around this time McMahan and Walford began writing together for the band's next record, creating six new songs which the band practiced throughout the summer of 1990. Slint entered River North Records in August 1990 to record Spiderland. At that time there were no vocals or lyrics prepared for the album, so the band wrote them while in the studio. The album's producer, Brian Paulson, was known for his "live" recording style in the studio, with minimal takes. Paulson recalled "It was weird while I was doing [Spiderland] because I remember sitting there, and I just knew there was something about it. I've never heard anything like this. I'm really digging this but it's really fucking weird."The recording sessions for Spiderland are reputed to have been difficult for the members of the band and were, according to AllMusic, "intense, traumatic and one more piece of evidence supporting the theory that band members had to be periodically institutionalized during the completion of the album." Rumors circulated that at least one member of Slint had been checked into a psychiatric hospital. Walford later addressed these stories in an article in Select by saying, "[We were] definitely trying to be serious about things, pretty intense, which made recording the album kinda stressful." The recording was completed in four days.
Question: What is the full name of the person that Todd Brashear replaced?

Ethan Buckler.

Passage: By the early 20th century, major river-control projects had begun to take place. Levees were constructed along the river in most urban areas, and Portland built concrete walls to protect its downtown sector. In the following decades, many large dams were built on Cascade Range tributaries of the Willamette. The Army Corps of Engineers operates 13 such dams, which affect flows from about 40 percent of the basin. Most of them do not have fish ladders.With development in and near the river came increased pollution. By the late 1930s, efforts to stem the pollution led to formation of a state sanitary board to oversee modest cleanup efforts. In the 1960s, Oregon Governor Tom McCall led a push for stronger pollution controls on the Willamette. In this, he was encouraged by Robert (Bob) Straubthe state treasurer and future Oregon governor (1975)who first proposed a Willamette Greenway program during his 1966 gubernatorial campaign against McCall. The Oregon State Legislature established the program in 1967. Through it, state and local governments cooperated in creating or improving a system of parks, trails, and wildlife refuges along the river. In 1998, the Willamette became one of 14 rivers designated an American Heritage River by former U.S. President Bill Clinton. By 2007 the Greenway had grown to include more than 170 separate land parcels, including 10 state parks. Public uses of the river and land along its shores include camping, swimming, fishing, boating, hiking, bicycling, and wildlife viewing.In 2008, government agencies and the non-profit Willamette Riverkeeper organization designated the full length of the river as the Willamette River Water Trail. Four years later, the National Park Service added the Willamette water trailexpanded to 217 miles (349 km) to include some of the major tributariesto its list of national water trails. The water-trail system is meant to protect and restore waterways in the United States and to enhance recreation on and near them.A 1991 agreement between the City of Portland and the State of Oregon to dramatically reduce combined sewer overflows (CSOs) led to Portland's Big Pipe Project. The project, part of a related series of Portland CSO projects completed in late 2011 at a cost of $1.44 billion, separates the city's sanitary sewer lines from storm-water inputs that sometimes overwhelmed the combined system during heavy rains. When that occurred, some of the raw sewage in the system flowed into the river instead of into the city's wastewater treatment plant. The Big Pipe project and related work reduces CSO volume on the lower river by about 94 percent.In June 2014, Dean Hall became the first person to swim the entire length of the Willamette River. He swam 184 miles (296 km) from Eugene to the river mouth in 25 days.
Question: What is the last name of the person to swim the river that governor McCall wanted more pollution controls for?

Ex Output:
Hall.
