Vocal Spectrum is a barbershop quartet from St. Charles, Missouri.
A distinctive feature of the quartet is tenor Tim Waurick's ability to sustain notes for upwards of 30 seconds,[2] and the tenor's and lead's incredibly high vocal range,[3] featured in many of the group's recordings and live shows.
The only championship that remains for Vocal Spectrum to win is the Barbershop Harmony Society's Senior quartet contest for which they will not become eligible until at least the 2030s (no member of a competing Senior Quartet can be younger than 55 years old, and the aggregate age of the quartet must equal or exceed 240 years [average age 60 or greater]).
On July 8, 2023, the quartet was inducted into the Barbershop Harmony Society's Hall of Fame.
[5] The group's Vocal Spectrum II recording was awarded "Best Barbershop Album" by the Contemporary A Cappella Society in April 2009.
