Like rock ’n’ roll, hip-hop is all about bravado. Without it, both forms are rendered impotent. Thankfully, Richmond’s Dr. Millionaire doesn’t have performance issues — his is a full-on erection of the almighty id. A decidedly profane affair, Dr. Millionaire’s strength lies in his clear and concise diction and rolling wordplay. Rhymes come hard and fast over his Tribe Called Quest-inspired beats in their pursuit of partying and panty-removal. Sounding like Rudy Ray Moore filtered through a prism of LL Cool J, Clipse and Kayne West, Dr. Millionaire’s devious tongue knows what it wants and knows how to get it. If you’re tired of sucker MCs, this is one homegrown rapper you need to check out. Dr. Millionaire brings his sexual healings to the Camel on Wednesday, Sept. 10. Doors open at 8 p.m. Free for adults 21 years old and older, and $5 for those who can’t legally drink but can die in wars. thecamel.org.
