Legendary producer David Axelrod’s solo album Heavy Axe is one of the finest outputs of the jazz-rock wave, which was the preeminent sound of the mid ’70s. With a little help from legendary players like Johnny “Guitar” Watson, Cannonball Adderley, and George Duke, Heavy Axe crisscrosses between lush funk sounds and full, round low end and majestic orchestral flourishes that made Axelrod’s sonic realm a goldmine for sample-hungry hip-hop beatmakers from the ’90s until today.
