100% agreed here. These guys could be as big as Metallica if they had a more creative manager in touch with the changing popular music landscape.
Those late 80s albums, as great as they are, would have been the time for them to go in even further on synths and really work towards a hit (Wasted Years was a step in the right direction). Instead, they doubled back on that sound and tried to sound more "street" and "rock" on NPFTD and FOTD. Then the 90s were the perfect opportunity for them to embrace a darker, more aggressive sound - instead they went sad and proggy.
With a proper management team behind them they could have really increased popularity in the 90s. That would, unfortunately, probably mean we wouldn't have gotten the reunion with Bruce, but just think of the possibilities!
