TonicEffect is a group of five talented musicians and truly gifted drinkers who transcend traditional a cappella roles to deliver an unexpected, exciting performance. Our modern, edgy music – including original mash-up arrangements, rotating vocal percussion and the occasional f-bomb drop – brings a new energy to the Bay Area a cappella scene. Why the name TonicEffect? In addition to being a musical reference and a nod to our favorite vodka mixer, if you look up tonic in the dictionary you’ll find: “(ton’ik), adj. Lifting the spirits, boosting energy and generally creating a feeling of well-being.” Not a bad goal, right?
