The Jazz Workshop

"Concerto for Billy the Kid" is a feature for pianist Evans, who starts with two-handed octaves that follow the score, before improvising on the changes of "I'll Remember April". "Ezz-Thetic" is a bop theme using the changes of "Love for Sale".[3]

The Allmusic review by Scott Yanow awarded the album 4½ stars and asserted: "Listening to the music, it is hard to believe that Russell only utilized a sextet... The ensembles are frequently dense, the harmonies quite original and there are often several events occurring at the same time; one would swear there were at least four or five horns being heard in spots... Russell was able to utilize some of the more versatile and technically skilled players of the era, several of whom worked regularly in the studios. Recommended".[4] The Penguin Guide to Jazz gave it a maximum four-star rating and included it in the recommended Core Collection of jazz albums, describing it as "an astonishing collection, including several pieces that stand as almost unique avenues of thought in the jazz language".[2]
