Wolf--

It all depends on what you like to listen to, but I would say that Magnum was one of the finest pomp/AOR acts ever. It is kind of hard to pick a similar band but I would say that they are akin to Kansas/Styx/Saga/Asia, but perhaps a tiny bit harder and more "direct" (don't ask, I can't really elaborate...)

I would definitely recommend "On a Storyteller's Night", or perhaps "Wings of Heaven", followed by "Vigilante" and then maybe "Chase the Dragon".
I would not recommend any of their very early stuff (Kingdom of Madness, II, Archive) to someone who wasn't really into them, as it tends to sound a little too dated and proggish. If you enjoy them, however, you may want to check out "Kingdom...".

They reached their pinnacle in the late 80s and their 90s releases are a mixed bag (Goodnight L.A., the ho-hum Rock Art). If you like what you hear, the more recently released discs by lead vocalist Bob Catley would appeal to you. They bring the best elements of the 80s work into the 90s (so to speak...). I hope this is helpful...

Regards,
