Both these bassists were around at the same time - Blanton appears to have had the bigger influence due to his stint with Ellington, the bass duets etc.. I was just wondering what people thought separated them? Pettiford for me, is more melodic -Blanton hits more roots in some of his solos, and they seem more scalar-based. I'm wondering about their harmonic language too, Blanton is always described as being very advanced, using lots of subsitutions. Apart from tritone subs, what else did he use (and for that matter Pettiford)?
