A track that many have been waiting for has finally seen the light of day. To be featured on Big Boi's forthcoming second solo album, Viscous Lies & Dangerous Rumors, today we get to hear "Lines," which notes assistance from A$AP Rocky and indie duo Phantogram. The somewhat funky and ambient single of course highlights bars from Big Boi and Rocky as Phantogram takes care of the hook. Check it out via the stream below and look out for more from Viscous Lies & Dangerous Rumors, due out on December 11. Also make sure to have a look at Phantogram's latest video "Don't Move."
