Kilgore College Sunday downsized its music department by filling a dumpster with CDs, vinyl records and sheet music.  Double Bass player John Porter says a friend tipped him off and Porter went to take a look for himself.  And what he saw, as he stood on the roof of the 20-footwide dumpster astonished him.   m wall to wall, six or seven feet deep was thousands of CDs, thousands of priceless musical artifacts and vinyl records."
