Jack Lewis is an American singer/song writer commonly known as the brother of antifolk artist Jeffrey Lewis and is almost always featured in his songs as well as for contributing to some recordings for Herman Düne. Jack began releasing solo music in 2002 under the name "Laissezfaire Lewis". Jack released "On a Shoe String" in 2006 and is currently playing music with Jeffrey Lewis & the Junkyard to which it seems his solo project has taken a backseat. The Junkyard''s most recent CD release "Em Are I" features a jazzy song "Upside Down Cross" written by Jack which gives hope for more solo music to come.
