The Flight of the Conchords' (Jemaine Clement and Brett McKenzie) self-titled album has debuted at number three on the US Billboard 200 chart, selling about 52,000 copies in its first week. The album came in just behind Leona Lewis, but nudged Ashlee Simpson out of the top three.
The album's performance has surpassed Crowded House's self-titled 1986 debut which reached No 12 on the US charts.
In New Zealand, the Flight of the Conchords' album debuted at number two, beaten to the top spot by Shihad's Beautiful Machine.
The Wellingtonian's album has now also topped internet download sales, according to industry website Billboard.
Most of the songs on Flight of the Conchords are taken from their television show, a comedy series set in New York where Clement and McKenzie play struggling musicians.
The comedy duo have already claimed a Grammy for their album, The Distant Future, which reached No 116 on the Billboard 200 chart.
