But if this erratic master had achilles heels on both feet, nothing could detract from the brilliant work of his best years, and he will be remembered as one of those unusual post-bebop jazz musicians who could deliver the idiom's intensity, intricate lyricism and wired momentum without sounding hurried or off-balance, and (like his model, Brown) give his most headlong improvised flights the poise and shape of a composition.— Culture | guardian.co.uk
Roach wasn't the first drummer to play bebop (that would be Kenny Clarke), but he was the first to explore its full rhythmic and harmonic potential, which is why he's recognized today, along with trumpeter Dizzy Gillespie and saxophonist Charlie Parker, as one of the architects of that 1940s musical revolution.— Entertainment Weekly's PopWatch
