  Hard bop is an extension of bebop (or "bop") music that incorporates influences from blues, rhythm and blues, and gospel, especially in saxophone and piano playing. Hard bop was developed in the mid-1950s, coalescing in 1953 and 1954; it developed partly in response to the vogue for cool jazz in the early 1950s and paralleled the rise of rhythm and blues. It has been described as "funky" and can be considered a relative of soul jazz. Some elements of the genre were simplified from their bebop roots.
  
  Miles Davis' 1954 performance of "Walkin'" at the first Newport Jazz Festival introduced the style to the jazz world. Further leaders of hard bop's development included the Clifford Brown /Max Roach Quintet, Art Blakey's Jazz Messengers, the Horace Silver Quintet, and trumpeters Lee Morgan and Freddie Hubbard. The late 1950s to early 1960s saw hard boppers form their own bands as a new generation of blues- and bebop-influenced musicians entered the jazz world, from pianists Wynton Kelly and Tommy Flanagan to saxophonists Joe Henderson and Hank Mobley. Coltrane, Johnny Griffin, Mobley, and Morgan all participated on the album A Blowin' Session (1957), considered by Al Campbell to have been one of the high points of the hard bop era.
  
  Hard bop was prevalent within jazz for about a decade spanning from 1955 to 1965, but has remained highly influential on mainstream or "straight-ahead" jazz. It went into decline in the late 1960s through the 1970s due to the emergence of other styles such as jazz fusion, but again became influential following the Young Lions Movement and the emergence of neo-bop.
