totally, not just roots and so forth.
but . . . . i assume this is not just a drums and bass duo, is that correct? so is he doubling the guitars? if so, and he's not the writer, that implies that he is subservient to the guitar players . . . supplying "groove" or what-have-you.
if he is the writer, it gets into a whole different thing. (maybe the guitars are doubling him.)
i guess what i'm advocating is a world where more bass players concern themselves with being band leaders and stretching the boundaries of what the instrument can do—and breaking the dogmatic strictures of what they're supposed to do . . .
yes, i have an agenda.
