The Super Audio CD (SACD) features two disc layers. One layer contains a standard version of the album that works on any CD player. The other layer includes high-resolution stereo and a 5.1 surround version of the recording that works on SACD-compatible DVD players and home theater systems. Both layers employ SACD's Direct Stream Digital (DSD) encoding process that samples the music 64 times faster than CD for unprecedented fidelity.Dark Side of the Moon, originally released in 1973, is one of those albums that is discovered anew by each generation of rock listeners. This complex, often psychedelic music works very well because Pink Floyd doesn't rush anything; the songs are mainly slow to mid-tempo, with attention paid throughout to musical texture and mood. The sound effects on songs like "On the Run," "Time" and especially "Money" (with sampled sounds of clinking coins and cash registers turned into rhythmic accompaniment) are impressive, especially when we remember that 1973 was before the advent of digital recording techniques. This is probably Pink Floyd's best-known work, and it's an excellent place to start if you're new to the band. --Genevieve Williams
