From an appreciation of Little Richard:
"...wailing with gleeful abandon"
Is there a better way to state what there is to love about rock music? I think not. This also explains why I have only slight patience for folksy music - Paul Simon is an important exception to the general rule, because he seems to be gleeful in his musings.
In related news, Alice Cooper was at Lords talking about cricket and how music companies no longer want to invest in new bands. Best statement: "That Pietersen, he's a bit a of a rock star, I hear." Second best statement: "Lady Gaga is the only real star these days." Third best: "People are afraid to be rock musicians today...if Paul Simon made Sargent Peppers today, no major music company would want to sell it."
