Back in 2007, in a hilarious post on the snarky-but-genuine music blog Idolator, Kate Richardson theorized that Rilo Kiley's artistic decline was linked to the shrinking length of lead singer Jenny Lewis' pants and skirts.

Correlation might not equal causation, but there was a comical synchronicity between the band's diminishing returns and Lewis' apparent transformation into a pop tart.

While Richardson rightly decried the lack of "bittersweet loneliness" and "prickly-yet-vulnerable lyrics" on Under the Blacklight, the band's Hollywood-slick 2007 LP, Lewis delivered those qualities in spades on the pair of solo records that bracketed Rilo Kiley's latest.

Rabbit Fur Coat and Acid Tongue established Lewis as a soulful country-rock songbird, an Emmylou Harris for the indie set. Whether backed by the Watson Twins or complemented by a bevy of famous friends (Elvis Costello, M. Ward, Zooey Deschanel), Lewis' solo output proves "bittersweet loneliness" and sultry confidence can coexist in one show-stopping voice.

She'll be in town Saturday for a standing-room-only gig on the Mershon Auditorium stage. The evening opens with Welcome to Van Nuys, a documentary about the making of Acid Tongue, followed by a set from Toronto twang posse The Sadies.
