I'll admit I'm not the most knowledgeable jazz fan. But I've been going back and listening to Nucleus as well as other works in Ian Carr's repertoire. Dusk Fire is one of many brilliant works.
“If we lived in a state where virtue was profitable, common sense would make us saintly. But since we see that avarice, anger, pride and stupidity commonly profit far beyond charity, modesty, justice and thought, perhaps we must stand fast a little, even at the risk of being heroes.” ~ Robert Bolt
