I saw Swans in the late 1980s at the legendary I-Beam club on Haight St. in San Francisco. They had a female singer at the time, and were an opening act for someone I can't remember now. While I was really into goth, industrial, experimental music then, I found them just aight. Honestly, I had no idea they were still together at this point, but am currently streaming their reunion album
The Seer. Yeah, still not a fan, sorry. I also kinda doubt that your date is going to love them, but stranger things have happened! If she does, it just might be true love...
