Born to a pair of entertainers in Las Vegas, Nevada on January 8, 1977, Lewis relocated to the San Fernando Valley as a child. Before she was ten years old, she appeared in a number of major commercials, and she wound up cast in Lucille Ball's 1986 sitcom Life with Lucy. Guest spots in a variety of sitcoms followed in the next few years, culminating with prominent roles in two 1989 films: The Wizard and Troop Beverly Hills. Lewis acted into the mid-'90s -- she wound up with recurring roles on the 1990 television show Shannon's Deal and 1991's Brooklyn Bridge -- but after appearing in the 1998 feature film Pleasantville, she turned away from acting.
That year, Lewis formed Rilo Kiley with Sennett -- the two were dating at the time -- Pierre de Reeder, and Dave Rock. After releasing an eponymous EP in 1999, the group replaced Rock with Jason Boesel and released Take Offs and Landings in 2001 on Barsuk. Another indie record -- The Execution of All Things, released on Saddle Creek -- appeared in 2002 before the group inked a deal with Warner to distribute More Adventurous in 2004.
Just as Rilo Kiley was receiving a push from a major label, Lewis fielded an offer from Conor Oberst for his imprint Team Love. Lewis hired the Watson Twins as support for Rabbit Fur Coat, her 2006 solo debut. Greeted by positive reviews and a major media push, Rabbit Fur Coat overshadowed all previous Rilo Kiley albums, but it also wound up giving a boost to the band's 2007 album, Under the Blacklight. Released on Warner proper, Under the Blacklight was Rilo Kiley's most successful record -- it wound up peaking at 22 on Billboard's Top 200 -- but the band splintered soon after its release. Although the official disbandment wasn't announced until 2014, a year after the odds-and-ends collection Rkives appeared, Rilo Kiley never recorded together again.
Lewis quickly turned her attention to her solo career, recording the rousing Americana record Acid Tongue. Written in part with her new partner Johnathan Rice, Acid Tongue debuted at 24 upon its September 2008 release. Lewis next teamed with Rice for I'm Having Fun Now, a collaborative album released under the name Jenny and Johnny in 2010.
Lewis hired Ryan Adams to produce The Voyager, an album that evoked the heyday of classic AOR. The Voyager debuted at number nine upon its July 2014 release. In 2016, Lewis, Erika Forster, and Tennessee Thomas formed the trio Nice as Fuck, releasing an eponymous album in June. Lewis returned to her solo career in 2019 with the March release of On the Line, which featured co-productions by Adams, Beck, and Shawn Everett. ~ Stephen Thomas Erlewine, Rovi
