Robbie Brauns - The original vocalist for Holy Soldier?

I've been told that Robbie Brauns is the original vocalist for Holy Soldier and can be heard on their demo.

I've done a bit of reading and found that possibly, he was also a singer for:
Hero (possibly displayed as H.E.R.O.) - They were on the California Metal compilation
Steel Vengeance (secular band)
Band of Wild Angels


Can anyone confirm this?

I really liked Hero from what I saw of them on the Metal Mardi Gras video

That would be pretty cool if he was the vocalist for both

I talked to Glenn whom was with him in HERO. They are still friends. He said Robbie wasn't officially "In" Steel Vengeance but did record on the "Never Lettin Go" album. He was in Holy Soldier. I did in fact see him play with them when I was a teenager. I believe I also saw him in HERO during a festival when I was a teen too.

Robbie did vocals for Holy Soldier 1985 to 1987 then set up Hero.There's a 1986 3 track demo of him in HS.It was on YouTube recently.I want to find out much more about Hero.Does anyone know if they ever released more than the 4 Songs in total....2 on California Metal,2 on Metal Mardi Gras?
They must not be confused with the Hero band from Alaska that did a 5 song demo and the 12 song Risen.I am pretty sure theywere 2separate bands but in the same style,same ery,and both Christian.It gets complicated sometimes don't it?
I also want to contact Glenn Rogers and Robbie Brauns but preferably by simple email.Does anyone have any info on that?
Blessings to you all
