well, encouraging such free-form exploration with their elliptical yet memorable themes. This quintet may have cut more adventurous records, but ESP remains one of their very best albums." Brian Morton noted: "E.S.P. is... the first record on which Miles seems to be flirting with rock. 'Eighty-One' has a strong backbeat, and the kind of regular, repetitive bass line and percussion that was characteristic of funk, and still considered somewhat infra dig in jazz. Any suggestion that Miles only began to explore a rock idiom on 1969's Bitches Brew misses the mark by a good four years."
