As an old fan of the band I guess I have to chime in here: forget about the boring hard rock band Jackyl, this has nothing to do with that. Instead, imagine a great mixture of Iron Maiden, Crimson Glory, Metal Church and Mercyful Fate and you've more or less got JACKAL.
The debut album "Rise" was an okay heavy metal (with cheesy hard rock lyrics) album, but not much more in my opinion.
However, the following two album, "Vague Visions" and "Safe Look In Mirrors", are classic power/heavy metal albums, that just kicks sooooo much ass! Brian Rich was on top of his game then - one of the best Bruce Dickinson sound-alikes in the world, a great frontman - and with Benny Petersen's awesome guitar playing, those two discs were something unique in my opinion.
Stuff happened internally in the band - I've heard several different stories to what exactly went down - but the matter of fact is that the band collapsed and it wasn't until recently that Brian returned with a new lineup and a new album ""IV" which honestly isn't THAT good
Now, for those who like the classic Jackal stuff (VV and SLIM) you might want to check out the first Narita album, which also had Brian Rich on vocals - that's probably the best Iron Maiden album that Iron Maiden never released
