Bill Haley and His Comets were an American rock 'n' roll band formed in 1952 by Bill Haley, a multi-instrumentalist, singer, and songwriter. They are often credited as one of the first rock 'n' roll bands to achieve mainstream success. Haley's music was heavily influenced by country, blues, and R&B, and their hits like 'Rock Around the Clock' and 'Shake, Rattle and Roll' remain cornerstones of early rock 'n' roll.
