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. All of Arf's members write and arrange for the ensemble, so the sound takes on lots of colors and styles, but the results are always fresh, fun, and a sophisticated when necessary. The Arf beast is Veronica Tadi, Andrea Shmandrea, Amy Charles, Glynis Davies, Sean Fitzpatrick, and Aaron Schumacher.
Arf has won 2nd place at both the 2013, and 2014 Harmony Sweepstakes LA regional acapella festival.
