 Penniman's hits of the mid-1950s, such as "Tutti Frutti", "Long Tall Sally", "Keep A-Knockin'" and "Good Golly Miss Molly", were generally characterized by playful lyrics with sexually suggestive connotations.AllMusic writer Richie Unterberger stated that Little Richard "merged the fire of gospel with New Orleans R&B, pounding the piano and wailing with gleeful abandon", and that while "other R&B greats of the early 1950s had been moving in a similar direction, none of them matched the sheer electricity of Richard's vocals.With his high-speed deliveries, ecstatic trills, and the overjoyed force of personality in his singing, he was crucial in upping the voltage from high-powered R&B into the similar, yet different, guise of rock and roll."
