Donald Christopher Barber (born 17 April 1930) is an English jazz musician, best known as a bandleader and trombonist. As well as scoring a UK top twenty trad jazz hit, he helped the careers of many musicians, notably the blues singer Ottilie Patterson, who was at one time his wife, and vocalist/banjoist Lonnie Donegan, whose appearances with Barber triggered the skiffle craze of the mid-1950s and who had his first transatlantic hit, "Rock Island Line", while with Chris Barber's band. His providing an audience for Donegan and, later, Alexis Korner makes Barber a significant figure in the British rhythm and blues and "beat boom" of the 1960s.
The 2017 line up is; Chris Barber and Bob Hunt (trombones); Mike Henry and Pete Rudeforth (trumpets), Bert Brandsma, Nick White and Ian Killoran (clarinets and alto sax, tenor sax, baritone sax). John Watson (drums), John Day (double bass), Joe Farler (banjo & guitar) Pat Halcox, trumpeter with the Chris Barber Band since 31 May 1954, retired after playing his last gig with the Big Chris Barber Band on 16 July 2008. Halcox and Barber were together in the band for 54 years - the longest continuous partnership in the history of jazz, exceeding even that of Duke Ellington and Harry Carney (48 years between 1926 and 1974). Tony Carter (reeds) also left the band at this time. Vic Pitt (double bass) retired in January 2007 after 30 years with the band. His feature duet with the drummers of the day - "Big Noise From Winnetka" was not only a feature of the Barber concerts, but also his time with the Kenny Ball band immediately before. When Amy Roberts joined the band in 2011, she was still a student at Royal Northern College of Music and thus not always able to be present. On several tours Bert Brandsma (reeds) replaced her. Brandsma joined as a permanent member in 2012. At St Luke's, London, on 9 June 2007 Barber appeared in the horn section of Nick Lowe's band during a concert. In 2008 Barber, along with Eric Clapton and others, were involved in a new co-operative record company, Blues Legacy. On 23 July 2009, Barber, Bilk and Ball played a one-off concert at Indigo2 at the O2 in Greenwich. The concert was presented by the British Music Experience. He performed at De Doelen in Rotterdam, the Netherlands, on 12 December 2010.

Did he appear during any other concert?

The Menominee (also spelled Menomini, derived from the Ojibwe language word for "Wild Rice People;" known as Mamaceqtaw, "the people," in the Menominee language) are a federally recognized nation of Native Americans, with a 353.894 sq mi (916.581 km2) reservation in Wisconsin. Their historic territory originally included an estimated 10 million acres (40,000 km2) in present-day Wisconsin and the Upper Peninsula of Michigan. The tribe currently has about 8,700 members. The tribe was terminated in the 1950s under federal policy of the time which stressed assimilation.
The Menominee Indian Reservation is located in northeastern Wisconsin. For the most part, it is conterminous with Menominee County and the town of Menominee, which were established after termination of the tribe in 1961 under contemporary federal policy whose goal was assimilation. The tribe regained its federally recognized status and reservation in 1975. The reservation was created in a treaty with the United States signed on May 12, 1854 in which the Menominee relinquished all claims to the lands held by them under previous treaties, and were assigned 432 square miles (1,120 km2) on the Wolf River in present-day Wisconsin. An additional treaty, which they signed on February 11, 1856, carved out the southwestern corner of this area to create a separate reservation for the Stockbridge and Lenape (Munsee) tribes, who had reached the area as refugees from New York state. The latter two tribes have the federally recognized joint Stockbridge-Munsee Community. After the tribe had regained federal recognition in 1973, it essentially restored the reservation to its historic boundaries in 1975. Many small pockets of territory within the county (and its geographically equivalent town) are not considered as part of the reservation. These amount to 1.14% of the county's area, so the reservation is essentially 98.86% of the county's area. The largest of these pockets is in the western part of the community of Keshena, Wisconsin. The reservation includes a plot of off-reservation trust land of 10.22 acres (41,400 m2) in Winnebago County, Wisconsin to the south, west of the city of Oshkosh. The reservation's total land area is 353.894 sq mi (916.581 km2), while Menominee County's land area is 357.960 sq mi (927.11 km2). The small non-reservation parts of the county are more densely populated than the reservation, holding 1,337 (29.3%) of the county's 4,562 total population, as opposed to the reservation's 3,225 (70.7%) population, as of the 2000 census. The most populous communities are Legend Lake and Keshena. Since the late 20th century, the members of the reservation have operated a number of gambling facilities in these communities as a source of revenue. They speak English as well as their traditional Menominee language, one of the Algonquian languages. Current population of the tribe is about 8,700.

Are there any major employers in the area?
