After my meeting with Alan, he managed to point me in the right direction. He help me understand that Classic Rock was all about being over the top, larger than life, being crazy and totally mad. He suggested that I use this as an essences to the ident.
So I have come up with an idea of a 3d stickman version of Slash plugging his guitar into an extremely large over the top speaker. He strums his guitar and then the speaker blows up, from the smoke that is left comes stadium lights and lasers. this is the followed by a sign saying "Classic Rock Week". The scene ends and then shows the MTV logo.
