A good way for Into Eternity to get big would be to tour like crazy. For some reason radio stations will not touch anything progressive. Even though Into Eternity does have alot of Death Metal in them theres still a progressive aspect (which to me is what makes them so great) they prob won't be played on the radio to much. But huge progressive bands like Dream Theater, Rush, and even Dave Matthews Band never get played on the radio and they sell out huge venues. I think thats what Into Eternity should do, it will be hard work but it will pay off big time later in there career.
