January 11. Not to be confused with the ’70s disco and ’80s roots-punk acts that share their name, these Gibson Brothers are one of today’s top traditional bluegrass bands, and were recently named “Entertainers of the Year” by the International Bluegrass Music Association. The group’s moniker is also a bit of a conundrum in that while its founding banjoist, Eric Gibson, and guitarist, Leigh Gibson, are indeed brothers, its erstwhile dobro player, Junior Barber, and bassist, Mike Barber, are father and son; mandolinist Joe Walsh (no, not Mr. “Rocky Mountain Way”) and fiddler Clayton Campbell flesh out the ranks. Raised on their father’s upstate farm, Eric and Leigh are steeped in deep country gospel and will certainly shake the Egg for this night of high harmonies and blistering breakdowns. (Solas and the Duhks do it up January 12; Jesse Cook jams January 18.) 7:30pm. $24. Albany. (518) 473-1845.
