Chuck Berry - Charles Edward Anderson "Chuck" Berry (born October 18, 1926) is an American guitarist, singer and songwriter, and one of the pioneers of rock and roll music. With songs such as "Maybellene" (1955), "Roll Over Beethoven" (1956), "Rock and Roll Music" (1957) and "Johnny B. Goode" (1958), Chuck Berry refined and developed rhythm and blues into the major elements that made rock and roll distinctive, with lyrics focusing on teen life and consumerism and utilizing guitar solos and showmanship that would be a major influence on subsequent rock music.
Little Richard - Richard Wayne Penniman (born December 5, 1932), known by his stage name Little Richard, is an American pianist, singer and songwriter, considered key in the transition of music from rhythm and blues to rock and roll in the mid-1950s. Penniman's hit songs of that period, such as "Tutti Frutti" (1955), "Long Tall Sally" (1956), "Keep A-Knockin'" (1957) and "Good Golly Miss Molly" (1958), were generally characterized by playful lyrics underpinned with sexually suggestive connotations. Penniman's innovative rhythm and blues and boogie-woogie-based music, charismatic persona, flamboyant showmanship, and distinctive vocals, which ranged from raspy shouts to screams, moans, croons, wails, and other emotive expressions, some of which were unprecedented in popular music, laid the foundation for rock and roll music, shaped the sound of rhythm and blues in the 1950s and helped to inspire at least two R&B subgenres: soul and funk.
