World of Bluegrass just picked up some extra national and local star power with the addition of Gillian Welch and Chatham County Line.
They'll both be part of the Red Hat Amphitheater main stage lineup during the International Bluegrass Music Association's Wide Open Bluegrass on Sept. 28-29.
Acclaimed singer-songwriter Welch will be part of an all-female "Special Collaboration," making what is billed as a special guest appearance alongside Molly Tuttle, Sierra Hull, Becky Buller, Alison Brown and Missy Raines. They're all the first women to win IBMA awards as instrumentalists, including reigning guitarist Tuttle and mandolinist Hull.

Meanwhile, there's also "Chatham County Line & Friends," featuring the popular Raleigh quartet that has become an IBMA fixture over the years. Among the "& Friends" appearing this time will be Mandolin Orange, who just played a sold-out show at Raleigh's NC Museum of Art this past weekend.
Flatt Lonesome, another IBMA award winner, also has been added to the Wide Open Bluegrass main-stage lineup. They've won vocal group of the year the past two years. Ricky Skaggs, Patty Loveless and reigning IBMA Entertainer of the Year Earls of Leicester were previously announced for the Red Hat shows.
This year's festival, the sixth year in Raleigh, will be Sept. 25-29.
Wide Open Bluegrass is the outdoor part of World of Bluegrass, featuring a free street festival as well as the Red Hat lineup. Preceding it is the "Bluegrass Ramble" of nightclub acts, keynote speaker Jamie Dailey and the IBMA Awards, hosted this year by the band Hot Rize.
Last month, IBMA extended its contract with the city of Raleigh to keep the event here through 2021.
Last year's World of Bluegrass events — business convention, nightclub performances, awards show and Wide Open Bluegrass — drew a total estimated attendance of more than 221,000. That generated $11.7 million in direct visitor spending, according to the Greater Raleigh Convention and Visitors Bureau (GRCVB).
The five-year totals for World of Bluegrass are more than 856,000 in attendance and $48.8 million in direct visitor spending.
