It’s March 2000. The millennium is in full swing. You’re driving around in your smokin’ hot Ford Taurus when “Absolutely (Story of a Girl)” by Nine Days comes on the radio. Life is gooood. Wanna time warp back to that feeling? You can, with “Story of a Song: A ’90s Unplugged Experience” at Paramount Theatre in Rutland. The one-night-only supergroup showcase features the lead singers of four impactful bands of yore — Chris Barron of Spin Doctors, the Verve Pipe’s Brian Vander Ark, Vinnie Dombroski of Sponge and Nine Days front man John Hampson — in a nostalgia explosion that feels more like an intimate garage hang than a curated concert.
