Aja

Steely Dan's 1977 album Aja blends jazz rock, jazz fusion and pop rock into a highly polished studio sound. Donald Fagen and Walter Becker pair complex chord progressions and literate, often sardonic lyrics with layered arrangements led by top session musicians; the record is characterized by crisp, meticulous production, jazz-influenced harmonies, prominent saxophone and electric piano textures, and careful rhythmic detail. Tracks move from tighter pop-rock songs like "Peg" and "Josie" to the extended, improvisation-friendly title track "Aja", showcasing the band's fusion leanings while retaining a smooth, accessible surface. The album exemplifies Steely Dan's studio-oriented approach and the late 1970s crossover between jazz and pop.
