[P] How to extract and count artist mentions from messy text data using LLMs

I have a long list of responses from a poll (in this case, we've asked our Facebook community we should have at our music festival). Our goal is to count the total mentions for each artist, but the data quality is low.

Here is some sample data:

Rena Guinn and the Gentlemen Blackwater Railroad Company
Mo' Mojo Music !!
We would love to be apart of this awesome event! Amazing!!!!!
The Rollin' Rust came threw at the #falldownfest last weekend …
