This documentary traces the band's relatively brief history, from formation out of the ashes of Green River, through line-up changes, struggles with drugs including singer Mark Arm's heroin addiction, and how the Mudhoney album Every Good Boy Deserves Fudge kept label Sub Pop from going out of business.

Arm supplies the film's most insightful commentary, speaking candidly about every challenge and success that Mudhoney experienced. Arm also explains how he inadvertently gave the grunge era its much-despised (by the musicians themselves) moniker and is shown at work at Sub Pop where he basically comprises the label's shipping department.

The film comes current with coverage of Mudhoney's 2009-10 world tour; if you have questions about this band it's likely that this film will fill in the blanks. Among others interviewed for I'm Now are Stone Gossard, Kim Thayil, Thurston Moore, Kim Gordon, David Fricke and Mudhoney alumni.
