a.squared is an electronic a cappella group that started at Yale University with the mission of reinventing a cappella as a new way of making music with the voice. This is accomplished by combining the maturity of the a cappella tradition with the wild uncertainties of cutting-edge music technology. During live performances, the voices are manipulated electronically by layering loops, punching in effects, and making five voices sound like forty. Consisting of five singers, one percussionist, and one mixer, a.squared strays from the common a cappella genre applying the same software that is used in electronic music to the traditional a cappella setting. a.sqaured’s approach opens up possibilities for producing new styles of music, a technique that is seemingly unheard of with acoustic voices.
