This is an EXTREME longshot, but I see people posting threads, asking questions about long forgotten comics of their youth on here all the time. So what the heck.
Sometime in the late 80's early 90's (1987ish to 1991ish) I used to buy a horror comic that I believe was in magazine format at the local drugstore. But I have absolutely no idea what the hell it was called.
The only story I can clearly remember reading was a story about a female vampire band. They got on stage to do their performance and locked all the doors in the concert hall. And then the three of them (I'm pretty sure it was 3) fed on the entire audience. Gave me nightmares for weeks. Only other story I barely remember involved evil mermaids of some sort. Like I said I barely recall it.
But I remember liking this comic/magazine and was curious if anybody can think of anything it might be so I could maybe browse ebay or the local comic conventions for some issues. Maybe even try and find the chick vampire band issue.
EDIT: I do believe the series was in B&W and the stories weren't really connected (but I could be wriong on both counts). And it was not the Vertigo series Vamps.
