“Somebody’s gonna get pregnant tonight!” Headlining this year’s Summer Jam for WorldOne Presents and V101, R&B icon Keith Sweat made it clear that much of his music is meant to accompany more… romantic activities. It was fitting that by the time he took the stage at Thunder Valley’s Outdoor Amphitheater Saturday night, the sun was long gone and there was a bright moon serving as backdrop to the evening. The other artists brought more of a high energy show to the stage, with Salt-n-Pepa performing not only their own music but samples from all manner of genre of music, courtesy the founding DJ, Spinderella, while D’wayne and Amar of Tony! Toni! Toné! raced back and forth across the vast stage getting the audience going at the start of the show. The sold out crowd of 4,000 fans in Lincoln, California appeared to be thrilled by the performances of all three artists, with DJ Gino bridging each act with his ongoing DJ set.
