that Yelawolf/Tech collab is kinda old news. tech talked about this news as a ustream a week or 2 back..... while he was in the Atlanta studio working on the song with Yelawolf. He took the video camera into the room where the live band was performing and the violinist was KILLING it. the song sounded pretty fucking dope... but only the instrumentals were being done... no lyrics at at the time
