Siouxsie and Budgie decided where to record the album by randomly placing a pin on a map of the world; the result was the U.S. state of Hawaii. Several songs are about their experiences in that region, including "Festival of Colours" and "A Strutting Rooster".
The song title "Inoaʻole" is Hawaiian for "no name". "Ice House" was inspired by an obscure television play, while single "Miss the Girl" was inspired by the J. G. Ballard novel Crash. "Dancing on Glass" was based on an Indian musical; during the studio session, the sounds of broken glass were created by Siouxsie and Budgie dancing on broken mirrors while wearing tough shoes.
Feast was released to critical acclaim. Paul Prayag of Record Mirror praised the album, awarding it a score of 4 out of 5 and writing: "Siouxsie and Budgie are wandering deeper and deeper into a jungle that looks like having no easily definable boundaries".Melody Maker described Feast as "an album of filtered brilliance, fertile, sensual and erotic; an album that, in its desperate naivety, attempts to articulate that moment when the monsoon ends, when the smell and the heat conspire in a perfumed mist and life sprouts instantly, green and luxurious".NME also hailed it: "The Creatures have assembled a multifarious sonic boom that is as various and kaleidoscopic as can be imagined. The humours of Sioux's frosty larynx are nakedly outlined against skins of sometimes fabulous quality. The drum sound on 'Ice House' must be one of the greatest on record".
