We All know about deterioration. We all know about breakdown- of friendship, of communication... I am all too familiar with the breakdown of human interaction - but what about fundamental breakdown. The There is a mathematical formula that can predict the deterioration of a nuclear substance over time- indeed the decomposition rate of a particular isotope forms the basis of our most accurate timepiece- the atomic clock. So what measures musical the deterioration from Beatles (1985) through Electro (1984-1988) via Velvet Underground and The FaithHealers, to Beltram (arguably not deterioration) and back to Led Zepellin (more a transgression...). Its an organic evolution, which by defenition is a deterioration or evolution (depending on your slanted mind/eyes)... could somebody please send me the formula...am i growing or shrinking, erroding, washing away in my own floods of doubt, of self criticism, of fear... or growing stronger? Evolving....
