Fagan and Becker would assemble a revolving cast of almost 40 session musicians to play on the album, consisting of some of the all-time greats, including Joe Sample, Larry Carlton, Wayne Shorter, Steve Gadd, Lee Ritenour, Timothy B. Schmidt — it's a long list. It's a Who's Who of session superstars.
The album name and its title track were inspired by a South Korean woman whom a high school friend's brother had married after serving in the army in her country. The chord progressions and melodies are so unique and so typically Steely Dan. The drum solo at the end of the title track by Steve Gadd is also astounding.
The album's title track, "Aja," opens with a serene piano introduction before building into a complex, multi-layered arrangement that features intricate drum patterns, subtle guitar lines, and a soaring saxophone solo. Other standout tracks include "Deacon Blues," a melancholy ballad with introspective lyrics, and "Peg," a catchy tune with a funky groove and infectious chorus.
Throughout the album, Steely Dan's lyrics explore themes of disillusionment, regret, and the quest for fulfillment. In "Black Cow," the opening track, the narrator laments the loss of a relationship, while in "Josie," the album's closing track, the band celebrates the freedom and excitement of a new love affair.
The album's meticulous production values, including multiple layers of instrumentation and intricate vocal harmonies, showcase Steely Dan's commitment to sonic perfection.
Founded by core members Walter Becker (bass) and Donald Fagen (vocals, keyboards), Steely Dan's popularity rose throughout the late 1970s on, and their seven albums throughout that period of time blended elements of jazz, rock, funk, R&B, and pop. Steely Dan created a sophisticated, distinctive sound with accessible melodic hooks, complex harmonies and time signatures, and a devotion to the recording studio. Becker and Fagen, with producer Gary Katz, gradually changed Steely Dan from a performing band to a studio project, hiring session musicians to record their compositions. The duo didn't perform live between 1974 and 1993. But their popularity nevertheless grew throughout the '70s as their albums became critical favorites and their singles became staples of Adult Oriented Radio and pop radio stations.
Overall, Aja represents a high-water mark in Steely Dan's career, showcasing the band's unique blend of jazz, rock, and pop influences in a polished, sophisticated package. The album has become a classic of the 1970s and remains a favorite among music lovers to this day.
