While it may serve as some sort of museum for those people who were young when it was the shining beacon of things new and exciting in music, since then it has become nothing more than an amusement park, a tourist trap. And punk rock doesn't need monuments.
Punk rock is not dead, and the passing of CBGBs will have no effect on the punk kids of today. For me punk rock is about youth and rebellion and creation and attitude, not worship of the past. I will take a moment to reflect on what CBGBs meant to the birth of punk, but hopefully I'll never hear its name mentioned again.
