In 1954, Roach and trumpeter Clifford Brown formed a quintet that also featured tenor saxophonist Harold Land, pianist Richie Powell (brother of Bud Powell), and bassist George Morrow, though Land left the following year and Sonny Rollins soon replaced him. The group was a prime example of the hard bop style also played by Art Blakey and Horace Silver. This group was to be short-lived; Brown and Powell were killed in a car accident on the Pennsylvania Turnpike in June 1956. The first album Roach recorded after their deaths was Max Roach + 4.
