Crazy Town Singer Comes Out of Coma

Sources tell TMZ, Shifty had been on breathing tubes since Thursday -- when he originally fell into a coma -- but was successfully taken off them Wedneday night.

We're told Shifty is now responsive -- even speaking sporadically -- but he's still not fully aware of his surroundings. He is still in the ICU.

As we previously reported, it's unclear what put the singer into a coma -- but several people close to him are convinced drugs were to blame.
