And the musical quality spearheaded by David’s guitar and voice and Rick’s keyboards established a fundamental Pink Floyd sound. We were comfortable with the music, which had had time to mature and gestate, and evolve through live performances – later on we had to stop previewing work live as the quality of the recording equipment being smuggled into gigs reached near-studio standards. The additional singers and Dick Parry’s sax gave the whole record an extra commercial sheen. In addition, the sonic quality of the album was state of the art – courtesy of the skills of Alan Parsons and Chris Thomas. This is particularly important, because at the time the album came out, hi-fi stereo equipment had only recently become a mainstream consumer item, an essential fashion accessory for the 1970s home. As a result, record buyers were particularly aware of the effects of stereo and able to appreciate any album that made the most of its possibilities. Dark Side had the good fortune to become one of the definitive test records that people could use to show off the quality of their hi-fi system. The packaging for the album by Storm and Po at Hipgnosis was clean, simple, and immediately striking, with a memorable icon in the shape of the prism.
