Yes, the JB's stands for James Brown's. This is his legendary backing group from the early 70'swith him in it as the frontman. Personnel include Fred Wesley, Bootsie AND Catfish Collins, Clyde Stubbefield (the "funky drummer") and Maceo Parker. So as you can proably imagine its as tight and as funky as f#@k.
Comparable to Zappa's backing bands, these guys were drilled like a military unit, and had many line ups, but were always unbelievable. As the great Rickey Vincent puts it. "The James Brown Revue invented funk, and the JB's perfected it".
This compilation includes The Grunt and Pass the Peas, but the highlight has to be the 12 minute long Doin' It To Death (they quite literally are). Its a slow cooked stew that gets better as it goes along, and even better over time on successive listens. It clicks and swaggers along like a predatory lover who knows they're sexy beyond belief and can get whatever they hell they want from you.
But above all its about the key change in the middle, when the band "Get into D". James Brown forecasts its coming, but then holds it off till the last possible moment, teasing us and repeating over and over "Get into D", "Get into D", "Get into D". Then finally it hits and its like an orgasm.
The dirtiest, sexiest funk I know.
