Robert Fripp's second team up with Brian Eno was a less harsh, more varied affair, closer to Eno's then-developing idea of ambient music than what had come before in No Pussyfooting. The method used, once again, was the endless decaying tape loop system of Frippertronics but refined with pieces such as "Wind on Water" fading up into an already complex bed of layered synths and treated guitar over whichFripp plays long, languid solos. "Evening Star" is meditative and calm with gentle scales rocking to and fro while Fripp solos on top. "Wind on Wind" is Eno solo, an excerpt from the soon to be released Discreet Music album. The nearly 30-minute ending piece, "An Index of Metals," keeps Evening Star from being a purely background listen as the loops this time contain a series of guitar distortions layered to the nth degree, Frippertronics as pure dissonance. As a culmination of Fripp and Eno's experiments, Evening Starshows how far they could go.
