Released in 1979, Star Walk was the last album that Graham would record with Graham Central Station for quite some time; in 1980, the influential singer/electric bassist officially became a full-time solo artist and soared to the top of the R&B charts with his debut solo single, "One in a Million You." And not until 1998's GCS 2000 would Graham use the GCS name on another album. If the name GCS had to be put to rest for a long time, at least the band went out with a bang on Star Walk. This excellent LP, which Graham produced himself, is full of sweaty, aggressive funk treasures; anyone who appreciates gutbucket funk would have a hard time not loving "Scream," "The Entertainer," and the single "(You're A) Foxy Lady." But not everything on this record is hardcore funk. "Tonight" is a lush Northern soul ballad, and the unexpected title song finds Graham getting into a synthesizer-driven Eurodisco groove -- if you didn't know better, you would think that Graham traveled to Munich, Germany, and hired Giorgio Moroder to produce the tune.
