New Orleans' recovery continues as Season 2 begins on Nov. 1, 2006, 14 months after Hurricane Katrina, but the rise in crime gives Colson and the police department all they can handle. Meanwhile, Sofia's emotional distance worries Toni; Albert must find a new place to stay; Annie returns from a national tour; and Delmond debuts his new album in New York, where Janette works in a trendy restaurant. The Dirty Dozen Brass Band perform.

Jazz Fest takes center stage in New Orleans, giving Treme residents a welcome respite from a challenging year.

Season 3 begins in the fall of 2007, as the neighborhood is shocked by police officers' response to a brass-band procession for a fallen musician. Meanwhile, Delmond and Albert experience different reactions to their new album; Toni finds a new ally in her ongoing crusade for justice; LaDonna is uncomfortable in her temporary lodgings; and in New York, Janette is reunited with Enrico Brulard.
