For more than three decades now, St. Louis Music Festival headliner Charlie Wilson has been making his way to the top of the R&B charts. As the frontman for the funk trio the Gap Band, Wilson hit it big with songs like "Outstanding" and "You Dropped a Bomb on Me." He launched his successful solo career in 2000 and has appeared as a featured guest on countless songs by artists like Snoop Dogg and Kanye West. His most recent release, Just Charlie, has already spawned the hit single "You Are." Fantasia and Eric Benét will be performing for the second time this year in St. Louis, along with the original lineup of En Vogue.
