Liv Tyler is tapping into her rock'n'roll roots which are showing through her cover of the INXS hit "I Need You Tonight". The song was produced by David Andrew Sitek who also worked with bands such as Yeah Yeah Yeahs, Liars, Foals, Celebration, and most recently Jane's Addiction (which might explain the gritty guitars). We are kind of feeling guilty at the office for having received a special vinyl recording of the song and a single CD, as the song itself not available yet for sale on iTunes at this point.
