From Austin Improv Wiki
Delta Burka was an improv troupe.
 Press BlurbTheir press blurb, taken from a 2010 application to perform at The Hideout Theatre:
Delta Burka was conceived by six improv-hungry individuals, after a post-class outing to Rio Rita one night. These six Level 2 classmates thought, "We respect eachother a lot and play so well together in class, so why not form a troupe?" And that's how it began. You couldn't get six people more different in one troupe, but that's why the love runs deep in Delta Burka.
 "What's Your Deal?"Their answer to the "What's Your Deal?" question on a 2010 application to perform at The Hideout Theatre:
We are working on a new form, but for now we mostly just do montage style long-form. We will probably stick to that for a while, as we are still developing our skills.
