I'm a guitarist and a rapper first and foremost, but I will always be grateful for the years where I worked almost exclusively as a bassist. It started off as a series of gigs just to keep things moving during a stagnant period, but during that time I developed massively in terms of timing, groove, vibe, and knowing when your moment is (and where it is NOT). 
 
Guitar helped me find my voice, but bass guitar helped me find my musical sense and made me an effective live communicator on stage.
