Drawing together some earlier material and a slew of new songs, Spacemen 3 tied everything together on the brilliant Perfect Prescription, the clear point of departure from tribute to psych inspirations and finding its own unique voice. Planned as a concept album, Perfect Prescription works where so many other similar efforts failed due to the strength of the individual songs, as well as the smart focus of the concept in question -- a vision of a drug trip from inception to its blasted conclusion, highs and lows fully intact. The bookending of the album makes that much clear -- "Take Me to the Other Side" is a brash, exultant charge into the joys of the experience, a sharp, tight performance. "Call the Doctor," meanwhile, is a pretty-but-wounded conclusion, husky singing and a drowsy mood detailing the final collapse. The many highlights in between beginning and end are so striking that the album is practically a best-of in all but name. Sonic's eventual work with Spectrum and E.A.R. gets clearly signaled via the majestic reprise of the Transparent Radiation single, here introduced by the swirling flange of an edited "Ecstasy Symphony," also originally from that release. Sonic's breathless delivery of the Red Krayola classic, combined with the elegant arrangement, is a marvel to hear. "Walkin' With Jesus," meanwhile, is practically the birth of Spiritualized, the much different earlier takes now become a reflective combination of acoustic guitar, two-note keyboard lines, and Pierce's yearning, aching desire. The intentionally nasty flip to that is the storming charge of "Things'll Never Be the Same," a call to arms (or injecting something into them) that's as disturbing as it is energetic, the compressed, violent rage of feedback and rhythmic charge a gripping listen. Guest performers from the Jazz Butcher family tree, including Alex Green on sax, help expand the record's sonic range even further. Further reissues include a rotating series of bonus tracks from contemporary singles.
