Arf started in 2013 as a live a cappella re-imagining of Genevieve Artadi's solo music, and in only a few months has evolved into a brand new beast with six heads to think up songs and arrangements, and fourteen limbs playing synths and drums. The Arf Beast is Kathy Hoye, Sean Fitzpatrick, Andrea Calderwood, Genevieve Artadi, Alexandra Domingo, and Jessica Freedman.
Arf has won 2nd place at both the 2013, and 2014 Harmony Sweepstakes LA regional acapella festival.
