I’m not a huge Rilo Kiley or Postal Service fan, but as far as I’m concerned, alt-rock thrush Jenny Lewis can do no wrong. Her new solo disc, Acid Tongue, doesn’t drop until Sept. 23, but right now, you can hear the whole thing streaming on her MySpace page. Like her Rabbit Fur Coat (2006), it’s a roots-tinged tour of the backroads of American spirituality, exploring sex and murder, faith and doubt, along with the able support of some famous guests. And like Rabbit Fur Coat, it’ll probably get stuck for months on an endlessly repeating loop in my iPod. Listen to the whole thing here, or get a taste of it in the video above, along with Lewis guest Ben Gibbard of Death Cab for Cutie and Postal Service.
