Usually when discussing a drum circle, the image that comes to mind is a bunch of bongos in a park, loosely arranged around one another and beaten in whatever rhythm takes the fancy of the crowd. But today a much more involved and equipment-heavy kind of drum circle is happening in Byron Bay, Australia, in honour of the numerical neatness of the date: 11/11/11.
Boredoms - a Japanese experimental noise rock band that originally formed all the way back in 1982 - is a big fan of dates that line up. Over the past four years, the band has led a massive performance involving a huge number of drummers on each of these matching dates: 77Boadrum took place July 7, 2007 (7/7/07), 88Boadrum on August 8, 2008 (8/8/08), Boadrum 9 on September 9, 2009 (9/9/09), and yep, Boadrum 10 on October 10, 2010 (10/10/10).
This year's event will involve a total of 111 drummers, 100 of which will be cymbal players. They'll be laid out as in the diagram below (click for full size version).
