Gavin Christopher Newsom was born in San Francisco, California, to Tessa Thomas (nee Menzies) and William Alfred Newsom III, a retired state appeals court justice and attorney for Getty Oil. He is a fourth-generation San Franciscan. His father is of mostly Irish descent; one of Newsom's maternal great-grandfathers, Scotsman Thomas Addis, was a pioneer scientist in the field of nephrology and a professor of medicine at Stanford University. Newsom is the second cousin, twice removed, of musician Joanna Newsom.
On May 14, 1991, Newsom and his investors created the company PlumpJack Associates L.P. In 1992, the group started the PlumpJack Winery with the financial help of his family friend Gordon Getty. PlumpJack was the name of an opera written by Getty, who invested in 10 of Newsom's 11 businesses. Getty told the San Francisco Chronicle that he treated Newsom like a son and invested in his first business venture because of that relationship. According to Getty, later business investments were because of "the success of the first." One of Newsom's early interactions with government occurred when Newsom resisted the San Francisco Health Department requirement to install a sink at his PlumpJack wine store. The Health Department argued that wine was a food. The department required the store to install a $27,000 sink in the carpeted wine shop on the grounds that the shop needed the sink for a mop. When Newsom was later appointed supervisor, he told the San Francisco Examiner: "That's the kind of bureaucratic malaise I'm going to be working through." The business grew to an enterprise with more than 700 employees. The PlumpJack Cafe Partners L.P. opened the PlumpJack Cafe, also on Fillmore Street, in 1993. Between 1993 and 2000, Newsom and his investors opened several other businesses that included the PlumpJack Squaw Valley Inn with a PlumpJack Cafe (1994), the Napa Valley winery (1995), the Balboa Cafe Bar and Grill (1995), the PlumpJack Development Fund L.P. (1996), the MatrixFillmore Bar (1998), PlumpJack Wines shop Noe Valley branch (1999), PlumpJackSport retail clothing (2000), and a second Balboa Cafe at Squaw Valley (2000). Newsom's investments included five restaurants and two retail clothing stores. Newsom's annual income was greater than $429,000 from 1996 to 2001. In 2002, his business holdings were valued at more than $6.9 million. Newsom gave a monthly $50 gift certificate to PlumpJack employees whose business ideas failed, because in his view, "There can be no success without failure." Newsom sold his share of his San Francisco businesses when he became mayor in 2004. He maintained his ownership in the PlumpJack companies outside San Francisco that included the PlumpJack Winery in Oakville, California, new PlumpJack-owned Cade Winery in Angwin, California, and the PlumpJack Squaw Valley Inn. He is currently the president in absentia of Airelle Wines Inc., which is connected to the PlumpJack Winery in Napa County. Newsom earned between $141,000 and $251,000 in 2007 from his business interests. In February 2006, he paid $2,350,000 for his residence in the Russian Hill neighborhood, which he put on the market in April 2009, for $2,995,000.

How long did he work there?

2004.

Jeremy Webster "Fred" Frith (born 17 February 1949) is an English multi-instrumentalist, composer, and improvisor. Probably best known for his guitar work, Frith first came to attention as one of the founding members of the English avant-rock group Henry Cow. He was also a member of the groups Art Bears, Massacre, and Skeleton Crew. He has collaborated with a number of prominent musicians, including Robert Wyatt, Derek Bailey, the Residents, Lol Coxhill, John Zorn, Brian Eno, Mike Patton, Lars Hollmer, Bill Laswell, Iva Bittova, Jad Fair, Kramer, the ARTE Quartett, and Bob Ostertag.
Fred Frith has used a number of different guitars, including homemade instruments, over the years, depending on the type of music he is playing. For the more structured and refined music he has often used a Gibson ES-345, for example on his solo album, Gravity. For the heavier "rock" sound, as in Massacre, he has used an old 1961 solid body Burns guitar, created by the British craftsman Jim Burns. On his landmark Guitar Solos album, Frith used a modified 1936 Gibson K-11 guitar (q.v. for details). For Frith's early unstructured music, as with Henry Kaiser on With Friends Like These, and his early table-top guitar solo performances, he used a homemade six- and eight-string double-neck guitar created by a friend, Charles Fletcher. Frith told DownBeat magazine in 1983: "It was the one and only guitar that he ever built ... he constructed it mainly out of old pieces from other guitars that I had, and for the body I think he used an old door." The possibilities offered by homemade instruments prompted Frith to start creating his own guitars, basically slabs of wood on which he mounted a pickup, a bridge, and strings stretched over metal screws. "The basic design of the instrument is supposed to be as rudimentary and flexible as possible," Frith said, "so I can use an electric drill to bore holes into the body of it to achieve certain sounds ... ." Frith uses a variety of implements to play guitar, from traditional guitar picks to violin bows, drum sticks, egg beaters, paint brushes, lengths of metal chain, and other found objects. Frith remarked: "It's more to do with my interest in found objects and the use of certain kinds of textures which have an effect on the string ... the difference between the touch of stone, the touch of glass, the touch of wood, the touch of paper - those kinds of basic elements that you're using against the surface of the strings which produce different sounds." In a typical solo improvising concert, Frith would lay a couple of his homemade guitars flat on a table and play them with a collection of found objects (varying from concert to concert). He would drop objects, like ball bearings, dried beans, and rice on the strings while stroking, scraping, and hitting them with whatever was on hand. Later he added a live sampler to his on-stage equipment, which he controlled with pedals. The sampler enabled him to dynamically capture and loop guitar sounds, over which he would capture and loop new sounds, and so on, until he had a bed of repeated patterns on top of which he would then begin his solo performance.

Was there anything interesting about there playing technique?
