Canadian/American singer/songwriter Justin Nozuka, 20, writes poppy tunes and sings them in an effete tenor. Missy Higgins (pictured at right), a more substantial artist than Nozuka, hails from Australia; her music alternates between moody, intimate post-folk and livelier acoustic pop. Also on the bill is cutie Aussie folkie Lenka. 8 p.m., State Theatre, St. Petersburg, $25. (Text by Eric Snider)
