Powerplay's "Avanti" is one such gem. I believe they are Dutch band. They had one album out here in the States. They sound a bit like the Outfield (4 years before they were out), a little bit like some of their fellow Dutchmen Golden Earring's more poppy stuff. The fretless bass player is amazing! Lead singer Jan van der Mey still plays out with a version of the band.!
I was amazed that there is quite a bit of their stuff on YouTube
Here's a few good tracks.
"Waste of Time" really sounds like a lost Outfield track
"Love Can Break Your Heart"
Here's a link to their website:
