One of the interesting versions of partisan politics I've noticed since joining the local open mic scene is between two apparently opposing camps in the music scene - those who play "original" songs versus those who play "covers". "Covers" is a term, uttered either under one's breath with a hint of shame (by the people playing them) or with a distinct tone of disdain and perhaps a spray of saliva on the "c" sound just for emphasis (by those staunch supporters of playing only originals), used to designate music composed by someone other than the performers themselves.
This distinction is a foreign one for me since I grew up in the classical music world, where the Great Composers Of All Time were revered and respected as part of my musical education. Some of these Great Composers were Bach, Vivaldi, Mozart, Brahms, Tchaikovsky, Sibelius, to name a few. I focused all of my attention on training and developing the technique required to execute the intentions conveyed in increasingly complex written notation, leading up to the Great Concertos. These were the truly epic compositions that required a tour de force of virtuosic technique and range of emotional expression imagined to be conveyed by the Great Composer.
