It's hard to get past the funny Steve Martin we all know from movies and comedy acts and think of him seriously playing music. And yet we have no choice but to move on because his new CD, titled The Crow, proves his transition to banjo pickin' is no joking matter. Having teamed up with a bluegrass entourage known as The Steep Canyon Rangers, Martin will visit the Q.C. for a performance at Blumenthal Performing Arts Center's newest venue, Knight Theater tonight. With special guest Dave Barry. $54 and up. 8 p.m. Knight Theater, 430 S. Tryon St. 704-372-1000. www.blumenthalcenter.org.
