Under the moniker Lady of the Sunshine, Aussie singer/songwriter Angus Stone takes a break from his partnership with sister Julia to reveal the darker, more rock-oriented side of his persona on Smoking Gun. The misty tones and textures of his main gig are de-emphasized in favor of fuzzed-out guitars, bluesy grooves, and obliquely disturbing lyrics. Stone strolls through his songs' ominous landscapes as both participant and tour guide, surveying scenes tinged with a psychedelic glow. His murmuring, slightly bleary vocals are mysterious and confiding, making even somewhat lighthearted tunes like “Big Jet Plane” feel prickly around the edges. The crunchy riffs of “White Rose Parade” and the title track suggest Neil Young jamming with Syd Barrett circa 1970. An eerie, childlike vibe creeps into “Jack Nimble,” setting things up for the windswept twang of “Kings Black Magic” and the simmering atmospherics of “Dead Man’s Train.” The closing track, “Lady Sunshine,” wraps Stone’s supple falsetto around a luminous acoustic guitar line that leads into a musical quote from the Wizard of Oz soundtrack.
