An inspiring and powerful underground non-comercial Rock Band from Seattle, WA. Formed in the late '90s at the famous 909.JOA (just off Aurora) Club. Orginal members include SeanDon, JC Milne, and Brent McDowell(since replaced). The bands name stems from that of a monkey-butler that was the clubs mascot at the time.
