Mach 4

Brooke Robinson - Tenor

Becky LaBella - Lead

Chris Dunbar - Baritone

Michelle Dunne - Bass

l-r: Becky, Chris, Michelle, Brooke

Mach 4 evolved into its current form over a period of a few years, and competed for the first time with its current personnel at the Harmony, Inc. International Contest in November 2016. Becky LaBella, who started barbershopping in 1976, has seen great success in the craft in both chorus and quartet. Brooke Robinson, Becky's daughter, has been singing for years, but recently started to sing barbershop, and IC&C with Mach 4 was her first quartet contest. Chris Dunbar also brings a wealth of experience to the quartet, and is especially well known for her past performances with Treble in Paradise. Michelle Dunne is a barbershop brat on both sides of the family. She sings bass like her daddy, and is happy to be singing alongside her friend, Becky, after years of wishing it true. Call Becky at 714-390-0597 - they'd love to sing for you!
