Holy Rickenbacker sloppy growly thunder! And the engineers didnt mess with it - try to pretty it up and lose that edge.
Bassist have a tough job - play repeated bars, play counter to the melody, and stay right there with the drummer.
How someone can do that AND sing? crazy. Like patting your head and rubbing your tummy.
Especially guys like Jack Bruce, Tim Bogert, and Squire. They often sang complicated melodies that were out of synch with the bass playing. Squire is mind-boggling at this.
