In an old episode of Key and Peele, the titular two wondered what ever happened to rap GROUPS? There are still plenty of rappers... But where are the rap GROUPS?
I bring this up, because having a full band is what's gotten me to this point. I play guitar, and my band has a singer, a drummer, a bass player, and a second guitarist. Without these individuals, I would still be nowhere. I don't know if it's feasible for you to start a rap group, as according to Key and Peele, rap groups are a thing of the past... but bringing in several other musicians to help cultivate my vision has helped me tremendously.
