Don’t miss blues, rock and soul tour de force Gary Clark Jr., who takes the stage in Portland on Thursday with an opening set from hip-hop/rap duo Blackillac. Clark’s three albums have earned him a total of six Grammy nominations, four of which he won. His most recent album, “This Land,” worked its way to No. 6 on the Billboard Top 200 chart, and the momentum of his career, propelled by steady touring, shows no signs of slowing down. And it’s extended to the big screen: He played Arthur “Big Boy” Crudup in Baz Luhrmann’s blockbuster biopic “Elvis.”

Peaceful Means
7 p.m. Friday. First Universalist Church, 479 Main St., Norway, free, donations accepted. peacefulmeans.net
Here’s a chance to see a new musical duo that creates lovely harmonies. Peaceful Means is singer-guitarist Leah Boyd and singer-pianist Heather Pierson, and their show will feature a blend of original songs as well as vibrant arrangements of ones you know. Acoustic strings, piano and percussion will be the backdrop for the pair’s vocals. The show is also a reunion of sorts; the women were in a rock band together in the early ’90s.
