Chicagoan Mark Messing is the Maestro of Chicago’s  “astounding circus punk marching band” Mucca Pazza. This week he and a few other Mucca Pazza-ians sit in as guest co-hosts and no doubt they’ll have some pretty outrageous music to play from their  personal collections.

Also, a conversation with David Brown, the leader of the Barcelona Spain based band Brazzaville.
