The Marian Circle Drum Brigade is a musical project started by Michael Bostwick of Pipe Choir, PC-ONE and P C III in 2010.

According to Bostwick, The Marian Circle Drum Brigade was inspired by his love of marching band drumlines ever since he was a child. When he was in high school he tried to join the marching band but due to his inability to read sheet music was denied the opportunity.
Inspired by this memory, Bostwick conjured up The Marian Circle Drum Brigade, a virtual marching band in the summer of 2010

The Marian Circle Drum Brigade is a project that features primarily a loud high energy drumline (performed entirely by Bostwick) and is accompanied by an aggressive industrial alternative vocal approach reminiscent of Ministry’s Al Jourgensen.  The Marian Circle Drum Brigade described by Bostwick as a combination of the Top Secret drum core and industrial alliterative metal band Ministry.

The Marian Circle Drum Brigade has released one self titled six song album available on Soundcloud and Free Music Archive.  The Marian Circle Drum Brigade's music is licensed under Creative Commons Attribution 4.0 International.
