The Rolling Stones : )
The big red mouth with its long tongue sticking out,has been the official logo of the longest-serving rock-and-roll band in the world since 1971.It means individual talent unified and magnified. That radical tongue symbolises the free spirit and expression that their music is known for. This logo is easily recognized in todays world. Music is the center point of almost all emotions that people hold and with that, many people look to music for security and support. People are often unable to represent themselves the way they would want to. This simple tongue is the almost the complete opposite. The tongue represents free spirit. The need to impress no one.
