You learn something new every day. I was having a discussion with web editor Chris Kornelis about artwork reproduction on vinyl-to-compact disc reissues. I handed him my copy of Duke Ellington Meets Coleman Hawkins, which had reprinted liner notes to such microscopic size they were nearly unreadable (and I have 20/20 vision, so you know they were bad if I had trouble making out the words).When Kornelis tried reading them, he noticed they were written by jazz critic Stanley Dance. Kornelis, having the appetite for knowledge he does, did a quick search for “Stanley Dance” only to learn that Dance is the critic cited for coining the term “mainstream” to describe a musical genre.Plenty of hyphen-weilding modern-day music writers try doing this everyday. But “post-core”, “punk-grass” and “shit-rock”, are child’s play compared to “mainstream”.
