Flat Mates Quartet

Flat Mates are London’s freshest mixed-voice quartet, combining the smooth charm of vocal jazz with the vibrant energy of barbershop harmony. Ali and Conrad come from the world of competitive barbershop quartet singing, and Kate and Anni compliment this sublimely by bringing classical and jazz influences to the group. The group's experience has taken them across the world, from California, to Hong Kong - from Alicante to Vienna. Flat Mates' collective experience spans prestigious vocal ensembles, jazz clubs, and competition stages. In 2025, they won the first prize at Holland Harmony Festival, and they are setting their sites on more international competition appearances in the coming months.
