The Norwegian/Swiss duo Lethe, aka Anna Murphy and Tor-Helge Skei, are releasing a two track stand-alone single Gamma / Delta on December 4th ahead of their new album out early next year, and we’re delighted to be able to premiere the video for the latter right here on Backseat Mafia today.

Delta switches between a myriad of styles including metal, triphop, electronic, experimental and more, but pulls the unlikely strands into something melodic and thrilling, despite it being shrouded in this bubbling anxious sounding accompaniment, with dribbles of percussion here and there, giving way to these heavy riffs as it hits the chorus.
