I am an architect/builder in chicago specializing in high performance/energy efficient design and passive building, residential to light commercial.  I have been playing trombone for the past 40 years and recently added sousaphone to my resume.  I currently play with the Jeff Weisfeld Band and the North Shore Chamber Orchestra.  I was delighted to learn of Christopher Bill, his fun compositions and his beautiful tone on the trombone and wish to help support his art as a fellow trombonist and supporter of creativity.  See my work at www.zenplusarchitecture.com
