For a show about rock ’n’ roll, “The Undeniable Sound of Right Now” is a little too well-behaved.

Admittedly, this new play by Laura Eason (“Sex With Strangers,” TV’s “House of Cards”) is more about the decline of a certain rock spirit, here represented by a Chicago dive about to celebrate 25 years of classic gigs, in 1992. But the venue’s under assault. Grizzled owner Hank (Jeb Brown), who’s still recounting tales about the Clash, has to contend with a greedy landlord who wants to raise the rent. Worse, rock isn’t the sound of right now anymore: Hank’s daughter, Lena (Margo Seibert, late of “Rocky: The Musical”), is dating one of those highfalutin’ DJs spinning for the masses (Daniel Abeles).

“He’s like you were then,” Lena tells dad. “That’s why you don’t like him.”

Gentrification, the switch from one musical era to another, the changing image of rebellion are all great subjects, but both the writing and Kirsten Kelly’s production are just a little too wholesome and tidy. Crank up the volume, please!
