It’s hard to picture what someone looks like from their voice alone, which is why before TV most people believed the President was a radio just like the one in their living room. Go see a favorite singer for yourself with today’s deal to the Snowstorm Music Tour 2012 featuring T-Pain and Gym Class Heroes at the NIU Convocation Center in DeKalb on Friday, February 10, at 6:30 p.m. For $19, you get one general-admission ticket (a $29.50 value before fees, or up to a $37.90 value online, including all Ticketmaster fees).

The Snowstorm Music Tour’s sophomore outing hauls a team of seven Top 40 artists across the tundras of the Midwest. Grammy winner T-Pain gets hips swaying and shaking and attracts crowds of robot groupies with his autotuned vocal prowess. Now touring behind his fourth album, RevolveR, the laid-back Floridian has stuffed his recent career with sing-along singles such as “5 O’Clock” and collaborations with Wiz Khalifa, Rick Ross, and 50 Cent.

Gym Class Heroes collects the catchiest elements of hip-hop, rock, and R & B and brings them to life with live instrumentation and an infectious sense of humor, which catapulted the group onto the national scene in the form of hits such as “Cupid’s Chokehold.” Outasight aims for similar genre-smashing appeal, Cris Cab wrangles Caribbean-influenced beats, and DJ Dextrious warms up the audience so no one suffers a sprained sense of rhythm.
