Anganok was a mini opera written with San Francisco artist, Spoonman, in 1991. The opera was performed only a few times and was not recorded. However, the instrumental track and an early rehearsal with Spoonman's vocals exist. The instrumental track had been pilfered for other uses (such as incidental music for the Uncle Willie companion CD), and an excerpt of the instrumental track was included as part of the fourth disc of Our Tired, Our Poor, Our Huddled Masses.

In 2009 both the full instrumental track and the rehearsal recording were released as digital downloads.
