Norwegian progressive metal act Leprous have always been one to push the boundaries of what’s possible in metal. With a gradual transition to proggier horizons, these dudes are no strangers to incorporating all manner of synths, keys, and ambient effects into their sound. And now, the band have released this behind-the-scenes video of vocalist and keyboard player Einar Solberg walking through his keyboard setup. And yeah, keyboards are cool and all, but the man runs his through a Kemper Profiler, which if you weren’t aware, is a guitar amp processor. And the results are pretty friggin’ sick.
