Turning 50 years old today, 3 + 3 proved to be a turning point in the Isley Brothers' creative direction. Moving from a trio to a sextet would be enough to change the sound of any group, but the addition of the supremely funky bassist Marvin Isley and particularly the Hendrix-infused guitar work of Ernie Isley hustled the band into a heavier, funkier, and slinkier direction.
The veteran Massachusetts-based heavy metal/post-grunge outfit's first proper set of new studio recordings in a decade -- 2019's largely stitched-together Final Transmission served as a potent eulogy for fallen bassist Caleb Scofield -- the Relapse-issued Heavy Pendulum is a robust and relentlessly creative beast that distills all of Cave-In's influences into sonic totality.
