THE composer George Russell is treating his stint through Sunday at Sweet Basil, 88 Seventh Avenue South, as a full-scale career retrospective, culminating with his latest large work, ''The African Game.'' In Wednesday's first set, Mr. Russell and his 15-piece Living Time Orchestra made their way through his first 23 years in the jazz world, from the 1945 ''Cubano-Be Cubano-Bop'' to the 1968 ''Electronic Sonata for Souls Loved by Nature.''

The constants in Mr. Russell's pieces are modal harmonies and a distinctive way of layering material; the parts of his arrangements slide into place like cantilevered architecture, with trumpet, trombone, saxophone, synthesizer and percussion lines all overlapping.

Mr. Russell also enjoys eclectic juxtapositions, from jazz and Afro-Cuban rituals in ''Cubano-Be, Cubano-Bop'' to African xylophones, electronic sounds, overblown saxophone, jazzy brass chords, blues guitar and funk bass lines in the Electronic Sonata.

The Sonata, which anticipated much of the jazz-rock of the 1970's, was the showpiece in Wednesday's first set. It builds from buzzing electronic sounds, through oozy slow sections, through brass fanfares, to a climactic battle between a funk vamp and an accelerating riff.

The Living Time Orchestra, which is partially drawn from Mr. Russell's students at the New England Conservatory of Music, was most comfortable with the Sonata's jazz-rock. Mr. Russell's earlier pieces, which are closer to mainstream jazz, didn't always swing enough. Although the band hit all the notes, the layers of the music were blurred. Of the featured soloists, the brooding trumpeter Stanton Davis and the energetic saxophonist George Garzone stood out.
