Tim O’Brien will kick off ORNL Federal Credit Union’s Summer Sessions concert series in Oak Ridge on Saturday, June 10. Opening for Tim O’Brien will be the Po’ Ramblin Boys, who were a crowd favorite during the 2021 series, a press release said.

O’Brien is based in Nashville. He is a Grammy-winning singer, songwriter, and multi-instrumentalist, and a lifelong devotee of bluegrass music with more than 40 years in the industry, the press release said. He started touring nationally in 1978 with Colorado bluegrass band Hot Rize, and his songs “Walk the Way the Wind Blows” and “Untold Stories” were bluegrass hits for Hot Rize, and country hits for Kathy Mattea. Artists like Nickel Creek, Garth Brooks, and The Dixie Chicks have covered O’Brien’s songs, and over the years, he has collaborated with his sister Mollie O’Brien, songwriter Darrell Scott, and noted old-time musician Dirk Powell, as well as with Steve Earle, Mark Knopfler, Dan Auerbach, and Sturgill Simpson.

O’Brien’s skills on guitar, mandolin, fiddle, and banjo make him an in-demand session player, the press release said. The International Bluegrass Music Association awarded him song of the year in 2006 and named him best male vocalist in 1993 and 2006. He was inducted into the West Virginia Music Hall of Fame in 2013 and into the Colorado Music Hall of Fame in 2022. Notable O’Brien recordings include the bluegrass Dylan covers of “Red on Blonde,” the Celtic-Appalachian fusion of “The Crossing,” and the Grammy winning folk of “Fiddler’s Green.” His duet recording “Real Time” with Darrell Scott is a cult favorite, the press release said, and he won a bluegrass Grammy as part of “The Earls of Leicester.”
