With the inception of the group in Minnesota, Cami and Mike formed The Hummin'Birds. Beginning as a trio with Cami Harris, Mike Silbernagel and Jim Michels, the group focused on authentic styles of traditional vocal harmonies supported by traditional acoustic instrumentation. The first recording produced at Ambient Sound Studio in St. Paul features guest fiddler Tom Schaefer. The Hummin'Birds moved on to Colorado playing weddings and events with many talented musicians across the Front Range. As daughter Claire grew up playing fiddle, she began joining them at local gigs. They focus on music over genre but lean heavily on the Appalachian and western traditions of bluegrass, old-timey and swing.
