Raven turns out to be a five piece womens group from the Scarborough area doh! Actually I have a cd of theirs that someone gave me some years ago, they are not half bad but I think they would describe their music as "World Music". ASo I take back what i said about it being a heavy metal band, the metal band have a much larger net profile. It appears that all the performers are local which is commendable and usually associated with free festivals
