Affiniti, a classical crossover group from Ireland, returns to the Tri-Cities on their Pacific Northwest holiday tour. The trio will play a Celtic Christmas Concert, with special guest appearance by Howard Crosby, nephew of Bing Crosby. Affiniti’s style is a blend of classical, rock and Celtic music. Crosby, a Walla Walla business owner, sings tunes from Bing’s era, including some of his most famous holiday songs. Proceeds benefit the non-profit Arts Center Task Force, sponsor of the Vista Arts Center building project.
