While strolling through Wicker Park this weekend, I ran across a mysterious rag-tag marching band that were dancing through the streets in mismatched thrift-store uniforms and playing everything from gypsy jazz to raucous dixieland. It turns out I witnessed a live performance by Mucca Pazza, Chicago's premiere circus punk marching band. So if you happen to see a motley crew of horns, woodwinds, drums, accordians, a guitar player with a speaker on a hockey helmet, and a sousaphone player with grey porkchops (who also happens to play the melodica and lead the band), you can smile knowingly and join the parade.
