The Northsiders are Chicago's hippest barbershop quartet. Last year's regional runners-up to eventual national champs The Sound Exchange, The Northsiders are no stranger to the Harmony Sweepstakes stage. They perform traditional and contemporary favorites with a nod to the Rat Pack era. They have finished "on the podium" every time out on the barbershop contest stage. Sit back, sip a martini, and enjoy these cool cats!
