KT TUNSTALL, THE STATE ROOM, Tuesday, Oct. 8, 8 p.m., $40

Scottish songstress KT Tunstall has developed quite the reputation as an excellent live act since first bursting on the scene with her debut 2004 single "Black Horse and the Cherry Tree." Her blend of pop hooks and aggressive folk makes for winning tunes, even when the lyrical content delves into the darker side of life. That's certainly the case on her latest release, Invisible Sun//Crescent Moon, a collection she recorded in two stints. The Invisible Moon half chronicles her emotions around her father's death and mortality, while the Crescent Moon half is more wide-ranging in theme. Expect a big dose of the new material Tuesday night, as well as a decade's worth of fine songs. Brian Lopez opens the show.
