The formation of killer BOB was an accident. When a friend (visual artist Gavin Gamboa) of drummer Max Jaffe came to New York City to play a show, he asked Jaffe if he had a group that wanted to play. Jaffe said yes, although no such group existed. This was on Monday. On Wednesday, killer BOB played their first show. Rounded out by guitarist David Scanlon and bassist Rob Lundberg, the trio went from experimenting with some of Scanlon's music in their free time to a singular unit in less than a week. After rehearsing and performing in the NYC area for a few months, the trio felt that their sound was missing something, and that something came in the form of tenor saxophonist Johan Andersson.
