Last year, I received from a friend a demo of a band called Dementia (from Ohio), and the name of that demo is "Plead or Bleed". At the time I looked for information about the band, but unfortunately I don't found anything about it. However, when I was turning some old demos here, I found one of the same name, also of a band from Ohio, but their name were Bloodbath. Listening to the demo I realized that it was the same material. So, I sent an email to that my friend asking if he wouldn't have confused and exchanged the demos when he sent to me, but he told me that not even because the rip was done starting from the original tape. He also said he would ask a friend from Ohio if he knew anything about it, but never answered me about it, nor my subsequent emails.
I began to suspect that maybe this band (Dementia) could be a kind of "embryo" (or pre-band) of Bloodbath...
There are some days ago, I found a blog that apparently did a special on some bands from Ohio, and I found another information about Dementia, that they were also from the same town of Bloodbath, Youngstown.
Also found these two images that make me believe even more than this demo wasn't released under the name Bloodbath:


For those who have the demo Bloodbath and want to compare (and for those who don't know too), here's a song coming from another source (with a superior quality to rips that I found floating around):
Dementia - Homicidal Assault
My other question is regarding a band (also from Ohio, but from Warren) called Decimator. According to the only information I found about the band, they were active in the late '80s and early '90s and released an LP (!) called "Do Unto Others". They are a solid Thrash band:
Decimator - Fatal Vision
If anyone knows of something and want to share, I'd be very grateful! Anyway, any information is welcome!
Thanks in advance! (and sorry for my bad english...)
