Impulse, 1961

"Three weeks after Explorations, Evans recorded as sideman on Oliver Nelson's great Blues And The Abstract Truth. The group included, among others, Eric Dolphy, a saxophonist from Los Angeles, whose very dissonant and extremely innovative phrasing went well beyond hard bop clichés. Dolphy was soon to be recognized, for his work with Coltrane and Mingus, as one of the most original heralds of the jazz avant-garde, contributing richly to the deconstruction and transformation of the current rhythmic/harmonic parameters of post-bop jazz. Once again the meeting seems not to have produced much of a reaction in Evans. He kept his own pace along that personal path which, in the space of a few months, would lead his trio to astonishing musical and artistic peaks. Perhaps in a less sensational way than Dolphy or Coltrane and some others, these would profoundly, and forever, change the concept of a piano/bass/drum trio, the “ethics" within group improvisation, and the interactive approach of a bass player or drummer in any type of group.

Evans' influence on other pianists and instrumentalists, already glimpsed by that time, was destined to gradually equal that of Bud Powell. However, his went much further as a result of the greater number of jazz piano aspects involved, such as voicing, melodic approach, the logic in shaping a solo, tone of the instrument in relation to expressive aims; not to leave out some aesthetic/historical aspects like the rediscovery of the "singing" potential of the piano, no small feature of the late-Romantic and Impressionist European tradition with which Evans generously enriched the jazz language."
