Instant Classic

As always, for the New Zealand national convention, BHNZ secures the talents of a world-class quartet.  This year Pan Pacific 2023 goes further than that - we have two headline quartets!  Both are international quartet competition finalists - Instant Classic winning gold in 2015, and GQ placing 3rd in the Sweet Adelines International Contest in 2020.

Instant Classic comprises David Zimmerman, Theo Hicks, Kohl Kitzmiller, and Kyle Kitzmiller. They are four good friends with a passion for barbershop harmony, a cappella music, and music education.  Be prepared to enjoy a variety of music from several decades and styles, including vocal jazz, musical theater, pop, and even R&B!

The quartet began singing together in college and first competed in the Barbershop Harmony Society (BHS) International Collegiate Quartet Competition in 2009. The group has since become the 2011 Cardinal District Quartet Champions, the 2012 International Collegiate Quartet Silver Medalists, and in Pittsburgh, PA they earned the title of the 2015 International Quartet Champions.  They have also been recognized in the Cardinal District as Quartet of the Year in 2012, 2014, 2015, and 2017. They are also all proud members of their home chapter in the BHS, the Greater Indianapolis chapter (Circle City Sound).

The group has performed all over the world, including in the United States, Canada, Sweden, the United Kingdom, and Australia.  They have appeared on National Television in the US, including opening for the Sing-Off Tour in Indianapolis in 2015 and performing as a featured act on the Today Show in 2016. They have also served as guest clinicians and teaching quartets for Youth in Harmony Camps (such as Camp A Cappella), Harmony University, and Harmony Academies around the world since their formation.  The group features arrangements by all four of the quartet members and has recorded two albums – “Instant Classic” and “Instant Classic: Start of Something Big!”  You can purchase hard copies of the albums at the end of the show or find their music through online music stores such as iTunes, Amazon Music, Google Play, or directly from their website.
