Some critics have suggested that this drummer had a particular affinity for female bosses, especially in the early years of his career. By the time he was 20-years-old, Clark had established excellent credits with Williams, as well the marvelous organist Hazel Scott and the superb vocalist Lena Horne, but he'd also laid down the freewheeling tempos required by tenor saxophonist Lester Young. This was the background where he learned the dynamics necessary to sustain force behind two of the loudest trumpeters in the history of this genre, both previously mentioned, as well as the gently tinkling Shearing. In the late '50s a modernist edge developed in the drummer's approach, perhaps inspiring maximum use of the "Clarke" spelling as well as the middle initial. Again he was a regular part of Williams' trio; he also joined forces with European piano experimenter Rolf Kuhn. Working with bandleaders such as Eddie Harris and Les McCann in the '60s and '70s, Clark began bringing various percussion instruments, including the party wrecking bongos, to recording sessions. A high point in his later credits is McCann's dreamy opus titled Invitation to Openness. ~ Eugene Chadbourne, Rovi
