I know it's pretty basic, but I want to narrow it down to the Chilis when they did Blood Sugar Sex Magik witht hat real funk sound..any ideas?

It's not exactly funk, but Primus is kinda like RHCP, they got some crazy ass bass lines.
if you go way way back with incubus; like fungus amongous and enjoy incubus, they were pretty funky.

which makes sense, seeing as rhcp were a major major influence on incubus.
