Last night at Tree Sound studios in Atlanta, Sean Falyon, Pill and CyHi performed a few songs to warm up for their performance tonight at Vinyl, the first in our vitaminwater uncapped Live! tour. Yelawolf, J. Cole, Big K.R.I.T., Kardinal Offishall, 8 Ball and Bubba Sparxxx were hanging out, too. Did they sleep over so they could hit up the party tonight? To see for yourself you'll have to RSVP here before 3 today. Full invite with all the details, after the jump.
