Scotty McCreery seems like a nice young fella. I have no idea if he really is, but central to his modern country appeal is a guy-next-door persona that his management has carefully cultivated since the Raleigh, N.C., native won “American Idol” in 2011. McCreery’s 2013 album, “See You Tonight,” is coated in the finest high-pro glow that money can buy in its desire to make the music of Hank Williams palatable for teenage mall shoppers. By that yardstick, McCreery is wildly successful. Tunes such as the rootsy lament, “Feel Good Summer Song,” the boy-wants-girl mellow rock of “Blue Jean Baby” and the album’s declarative title track are catchy Top 40 ditties designed for maximum airplay. McCreery unleashes his dirt-free brand of here-and-now country on the masses Thursday, Aug. 21, at the Innsbrook Pavilion. Gates open at 5 p.m. Admission is $20-$99. innsbrookafterhours.com.
