Could it have been this person?[Phat Man Dee/Mandy Kivowitz] is a stylist, a diva, a circus performer, a punk-rock cellist, a cook at the annual Burning Man festival (a desert gathering of artists and/or freaks in the sweltering heat of Nevada that ends every year in a fire) and a belly dancer who handles a snake named Cat A. Tonic.
Or maybe this person? She has also performed at Burning Man, but I don't know what year(s).
[Zoë Keating] she uses live electronic sampling and repetition in order to layer the sound of her cello, creating rhythmically dense musical structures.
There's also a beatboxing cellist who's performed at Burning Man, although I doubt that's what you meant.
I wasn't there, so I don't have any idea. Just throwing out a few leads I found on the Google. Your question intrigued me.
If you want drama to stop following you everywhere, try letting go of the leash.
