Herb knows about obsession.
His experience in this area used to sometimes compel him to do very silly things like make CD's and stuff. 

Herb's debut CD, Failure (1998) is a concept album about failure. Artistic failure. Commercial failure. Successful failure. 

Herb's second CD, Another (2004) is another concept album about another concept album. See also self-referentialism.

Herb and his longtime musical collaborator Mark Briggs -- working under the name of Hmmm... -- released an album based on improvised material, I Only Want Love (2002).

eyes (2006)  is a DVD collections of excerpts from live performances by Herb's multimedia improvised art ensemble, dud.
