Jaco Pastorius started as a drummer and then moved to bass. In that crossover, he held tightly to his initial drumming bent and incorporated rhythm into his playing, frequently playing off the drummer to add complexity to the music's rhythms. He also used a sequencer to sample his bass as the rhythm track for his solos. I am guessing it would have been fascinating to image his brain and compare it to both drummers and non-drumming musicians:
