Quadratic Audio is one of the newest Quartets in the Harmonizers Chorus. Formed in 2013 after getting reacquainted at their Westwood HS reunion, Duncan Scott (Lead), Thom Olmstead (Bass) and Bob Pennell (Baritone) discovered their mutual love of barbershop harmony. They sought out a fellow choir member, Greg Grace (Tenor) and Quadratic Audio was formed. Bringing their talent to the competition stage, they entered the 2016 Arizona Division Quartet contest held at Skyline High and came away as the 2016 Arizona Division Novice Quartet Champions, the second time in 5 years that a quartet from the Mesa chapter has won the award. Quadratic Audio hopes to be competing in the District Quartet contest in Riverside, CA this fall.
