January 1955

Bo Diddley released his debut single Bo Diddley on Chess Records, introducing the syncopated 'Bo Diddley beat' — a shave-and-a-haircut rhythm derived from African and Afro-Cuban traditions. The beat became one of the most sampled and influential rhythmic patterns in rock and pop history.

By the mid-1950s, John H. Johnson's Ebony and Jet magazines were reaching millions of Black American readers, providing positive images and coverage of Black achievement unavailable in mainstream media. Jet's coverage of the Emmett Till murder — publishing the open casket photograph — became one of the most consequential editorial decisions in American journalism.

The Platters released Only You on Mercury Records, one of the first R&B doo-wop records to achieve massive mainstream pop crossover success. Lead singer Tony Williams's soaring tenor and the group's polished presentation helped define the vocal group sound of the late 1950s.

Sixteen-year-old Etta James recorded her debut single Roll With Me Henry (also released as The Wallflower) as an answer record to Hank Ballard's Work With Me Annie. It reached number one on the R&B chart and launched one of soul music's most powerful voices.

The Platters' The Great Pretender became their first number one pop hit, an unprecedented achievement for a Black vocal group in the mid-1950s. The record reached the top of both the R&B and pop charts simultaneously.

Willie Mays hit 51 home runs in the 1955 season, leading the National League and establishing him as one of the premier power hitters in the game. Combined with his extraordinary defense and speed, Mays's 1955 season reinforced his reputation as the most complete player in baseball.

LaVern Baker released Tweedle Dee on Atlantic Records, one of the definitive early rock and roll records. When Georgia Gibbs covered the song note-for-note and outsold Baker, the incident became a symbol of how white artists profited from Black creativity through 'cover versions.'

Anderson becomes the first Black singer at the Met.
