The irreverent HBO music-comedy series, “Flight of the Conchords,” starring New Zealand’s “fourth most popular folk-parody duo,” kicks off a 10-episode second season Monday, Aug. 3 at 11 p.m. on HBO and 10 p.m. on HBO Signature.

Fans can also complete the entire season over four consecutive days on HBO Signature from Aug. 3 to 6 at 10 p.m. For more play times, log on to www.hboasia.com.

Featuring the Grammy award-winning music-comedy duo Jemaine Clement and Bret McKenzie (collectively known as Flight of the Conchords) as fictionalized versions of themselves, this series revolves around the adventures of transplanted New Zealanders, Jemaine and Bret, who live on New York City’s Lower East Side and split their time between seeking venues where they can perform and awkwardly courting women. Sometimes finding it easier to express themselves with music, they are apt to break into song at a moment’s notice.

Over the course of the new season, Jemaine and Bret resort to a variety of unconventional strategies in an attempt to jump-start their lives and career, including: Taking desperate measures to pay the bills; starting up a gang; and even dating an Australian – a taboo in New Zealand. Their efforts rarely yield dividends, but do spawn new tunes about life, love and the pursuit of an elusive music video.

Among the familiar faces rejoining Jemaine and Bret for the second season of “Flight of the Conchords” are: Rhys Darby as Murray, who still works at the barebones New Zealand consulate and serves as their inept manager; Kristen Schaal as Mel, their married, obsessive fan, and David Costabile as Doug, Mel’s long-suffering husband; Arj Barker as their (only) friend Dave, who works at a pawn shop and lives with his parents; and Eugene Mirman as Eugene, their meddling landlord. Among the guest stars in this new season are Academy Award nominee Seymour Cassel, Emmy nominee Jim Gaffigan, Greg Proops and Kristen Wiig.

“Flight of the Conchords” received four Emmy nominations in 2008, including Outstanding Directing for a Comedy Series (James Bobin) and Outstanding Writing for a Comedy Series (James Bobin, Jemaine Clement, Bret McKenzie).

Created and written by the duo and James Bobin, the debut season of the series sparked critical raves, with the New York Times calling the show “very funny” and “deliciously absurd.” Rolling Stone hailed it as “hilarious,” while the San Francisco Chronicle termed it “the funniest thing you’ve seen in ages,” as well as “brilliant,” and the Detroit Free Press noted that the show is “charming and rambunctiously clever.”
