Austin Improv

Can anyone point me to solo (or duo, but self-accompanied, as opposed to one singer-with-accompanist) musical/singing improv acts? Ones where the songs are made up from audience suggestion/interaction of some kind? I'd love to know who else is doing this, and look at some video, so I can figure out what to do with my brand new troupe-band-thing. I'm particularly interested in women who do this, but really, anyone. Thanks!

Jill Bernard's Drum Machine is one of the most incredible things i've ever witnessed. she occasionally uses a live accompanist, but mostly has an actual drum machine with different beats programmed into it. and Indigo Shift is a trio, but if we can offer any advice let me know!

Loungeasaurus Rex from Minneapolis has an accompanist (at least when he plays OoB down here he does), but is great and worth mentioning based on how closely his act otherwise meets your criteria.

Mark Baratelli is one,

I can't find any "Jolley on the Spot" which was Lisa Jolley who inspired me to create Drum Machine.
