Rising Brazilian star Luiz B, whose "Thought" was a standout on Silk Sampler #2, returns with the elegantly titled "Song of Life." The Original Mix begins with the song's central motif, a catchy Spanish guitar riff, upon which a gentle rhythm is built. Deep pad sweeps and a low-pitched, yet resonant lead synth add additional body to the mix. As one would expect, Luiz B's alternate "Club Mix" packs a bit more punch, with heavier beats and a stronger bassline. Further, unlike the original, the club mix continues to crescendo post-break, as additional melodies, basses, and even vocal samples are presented in the latter half of the tune. On the first of two remixes, Australian artist Approaching Black [Armada, Arctic Wave] makes his Silk debut, with yet another refined progressive classic. In vintage form, he succeeds in infusing the original with an uplifting new lead, as well as a stunning array of additional side melodies and string-based transitional effects. Silk veteran Soundstorm, whose original tracks "Iris" and "Contact" continue to represent some of the label's proudest work, rounds out the package with a more subdued take. A veritable master of down-tempo progressive, Soundstorm once again proves his uncanny ability for subtle rhythmic development and rich, emotional sound design.
