While the iconic uniforms worn by the original barbershop quartets of the 1920s have gone the way of the dinosaur - colorful striped vests with boater hats - the style of music lives on.
Pop singers, like Christina Aguilera, have emulated the barbershop style with its distinct use of the "ringing chord," or the acoustic skill of expanding the sound of sung note to accomplish that loud, ringing effect (another thing Christina does quite well). The barbershop style is currently undergoing a revival, and popularity is picking up once again.
The young women of the Towson University GQ Quartet are taking the style to another level. The pros would have a member play piano on the side, but these girls do it a cappella. Now, that's talent.
