Puddle of Mudd singer Wes Scantlin went berserk during a recent Dallas show, flipping off the crowd and throwing his mic and water into the audience.
So Wes didn't exactly throw "half of stage," but the fury coming out of him sure made it seem that way. According to a TMZ report, the cause of Scantlin's rage remains unknown.
As the video below clearly shows, Wes might've had some technical problems with the microphone, after which he threw the mic into the crowd, started flipping everyone off and got into a verbal fight with certain members of the audience. After the crowd started throwing drinks at him, the vocalist fired back with water from the stage.
Near the end of the video, Wes can be seen taking his shirt off and calling audience for a fight, shouting something along the lines of "Come at me bro!" Check out the clip below for details.
