Frank says:

The concept of the rock-guitar solo in the eightees has pretty much been reduced to: Weedly-weedly-wee, make a face, hold your guitar like it's your weenie, point it heavenward, and look like you're really doing something. Then, you get a big ovation while the the smoke bombs go off, and the motorized lights in your truss twirl around!" -- The Real Frank Zappa Book.
