How do I rectify this situation? >chatting with two female

Yeah, I say you should go for it. Explain the situation. Sounds like there might be a chance that she'll assume you're lying and that she's just your backup and you're doing damage control, but just try not to come on too strong or too desperate and see how things go from there. If she says no, maybe don't push it too hard and just let it drop for now.

I really hope your reply was along the lines of "excuse me? What are you talking about?" if shes assumeing you're asking her out you should be shutting her the fuck down right then and there.

This. It's obviously too late for damage control but you should have immediately replied that you weren't actually inviting her, merely stating that you were looking for someone to go with.

>the one who silently witnessed this horrible debacle
Made me kek, thanks.

But yeah, ask he other one out and explain that you are a bit of an autist.

Chat with the two ladies again, as soon as possible. Say nothing about this at all until just before the chatting is concluded.
Then, and only after you're sure that you have the undivided (or at least minimally distracted) attention of BOTH girls, casually say
"btw, when I mentioned the Sigur Ros show, I hope you didn't think I was inviting (with a look of mild distaste at Cuntface) YOU. I was actually hoping that (with a look of indifference tinged with just the barest hint of interest) Crush, are free and would like to go"
or something along those lines
